Sai Bharat Batchu

A post by X user Naveen Kopparam has gone viral, revealing that a dosa seller near his home earns over ₹20,000 daily, totaling ₹6 lakh a month, and takes home ₹3-3.5 lakh after expenses—all without paying income tax. This sparked debates on social media about the disparity between vendors and salaried employees in India. Kopparam noted that while the vendor pays no taxes, a salaried employee earning ₹60,000 monthly pays 10% as tax. The post raised broader concerns about income tax policies and tax evasion, with users questioning similar practices by professionals like doctors and traders. #ViralPost #DosaSeller #StreetFoodIndia #SocialMediaDebate #IndiaEconomy #EarningsDisparity #SmallBusinessStories #marketinggrowmatics #smallbusiness #smallbusinessowner #startups

I come from a Layoff Batch 😞 (Tier-3 College) I didn’t receive a PPO from Amazon. I had to work a 10 AM to 7 PM shift 😬 (not counting the commute time) But despite that I never gave up. Deep down, I knew my goal was to be part of an MNC. 🌟 So, I created this strategy for Myself 👇: 📌 Started checking job portals and created a well-structured profile. 📝 📌 ⁠Applied to at least 20 jobs daily, either through referrals or recruiters. 📤 📌 Solved at least two DSA questions a day (one medium, one hard, or one easy). 🔍 📌 Stuck to one specific DSA sheet instead of hopping between multiple sheets. 📑 📌 Continuously updated my resume with projects. 🔄 It sounds overwhelming because it was!😅 At this time, my applications were Rejected, I Failed Interviews, Struggled with Consistency… And things got really difficult to manage but I didn’t let it stop me💪🏻 If you’re also feeling the same, don’t give up and don’t worry, you’re not alone. I had to create my path on my own but you can save the efforts with 1:1 support and guidance from experts.

Time to take off from Uber. It seems like they have taken Eventual Consistency too much into consideration. I booked the cab at 6:30 PM. I received the driver's call at 8:45 PM. I am surprised and the driver is surprised. What I got : Penalty of Rs 78.87 What the driver got : Plenty of frustration What Uber got : Brokerage This is not the first time, I had a bad experience with Uber. Once I booked Uber Premium , I got Maruti Suzuki 800. That was the first time I deleted the app, this is the second time. Uber , do something, you guys are hiring Candidate Masters. Have a good hire on Product Managers too. #Uber #Bangalore #EventualConsistency #Betting #on #Rapido

“My worst technical interview experience” . While trying to switch, I interviewed at Coinbase for the role of SDE 2. Now, let me clarify, the issue wasn’t with Coinbase—it was my incorrect expectations and irrelevant preparation. I assumed it would be a standard DSA round, but it was a Q coding round. I didn’t clarify with the recruiter and wasted time optimizing a straightforward problem. The real test was applying OOP concepts and refactoring. 🔹 Why was this so bad → I could have done well if I had understood the interview expectations and not been stuck in the "Leetcode mindset." 🔹 What I learned → Always clarify what concepts will be tested in the interview and read about others' experiences to prepare. However, finding detailed interview experiences isn’t easy. Many are vague, and don’t cover the specific challenges you face. That’s why it’s better to prepare directly with senior engineers from your target companies.

Few people join as a SDE-1 and within a span of ~7 years, they promote to a very senior level(L6 equivalent to Staff Role) in a company whereas same achievement is hard to realize when you're switching companies. So, what makes these employees so special? A few points: - They joined these companies as SDE-1 - Implemented projects end to end - very pro-active in all things: reviews/discussions/coding. - highly biased for taking actions (critical skillset for growth) - were lucky enough to some extent in getting good projects - were hard working enough to find optimizations & propose as new projects in the product - filled with lots of motivation & drive: showing true ownership at the deepest level one could possibly imagine Staying in a company helps you build context over the years, which the lateral hires within few months might or might not be able to grasp. This post is just a reminder: Switching would probably make money but staying in a company with a little bit of luck can do wonders(both money & role). PS: I did 2 switches in my career and I can relate with this post.

“SDE ke liye system design aata hai” 🤔 Yes, they do ask. It’s often assumed to be something only senior engineers need to know, but many companies now include it in their interviews, even for junior and mid-level roles. If you’re preparing for an SDE interview, make system design part of your plan along with DSA, behavioral questions, and mock interviews. <> Start with the basics Understand the fundamentals of scalability, latency, throughput, and availability. You don’t need to be an expert, but knowing how these work and where to use them is crucial. <> Practice simple use cases Start with smaller problems like designing a URL shortener or a rate limiter. These are often asked in interviews and help you build confidence. <> Mock interviews Practice with peers or mentors. Even if you don’t know everything, explaining your thought process clearly can leave a good impression on the interviewer. Don’t brush it off as irrelevant—it could be the one thing that sets you apart. And if you're looking to boost your interview skills and achieve your career goals, consider Tutort Academy.

"One of the most expensive operations in any startup is cloud costs, and a person sitting in the US pays the same price as an Indian. Is it fair?" These were the words of Bhavish Agarwal, founder of Ola and his current venture, Krutrim AI. But Cloud providers like AWS do provide region-based pricing? So, is that claim correct? My take on that is that it really depends. Yes, AWS offers region-based pricing, but upon closer examination of the AWS pricing calculator, we can see that some services, like API Gateway and others, cost the same regardless of location. In fact, the prices of some services are higher in India compared to the USA. For example: EC2 t3.medium (on demand) -> N. Virginia (us-east-1): $30.37/month -> Mumbai (ap-south-1): $32.7/month So, yes, Indians have to pay almost the same price as US citizens. Given that India is a developing country, the concern is valid. But why is this the case? Is it because hardware costs the same? That is, do servers placed in different data centers cost the same for the company? Please let me know in the comments if you have insights on the same. I currently don't know about their unit economics, but if intellectuals like Bhavish are highlighting the concern, it should be a valid one. And here was his solution: Krutrim Cloud. The recent drama of his LinkedIn post further accelerated his concern, and he has finally decided to completely shift his company from Azure to his own venture, Krutrim Cloud. Not only this, but in a recent tweet, Bhavish highlighted the crucial importance of India's data for our citizens. We should have sovereignty over our own data. The country holds immense potential and a wealth of information that can greatly benefit the population. What we urgently need is to digitize our data. To truly gain control, we must have authority over our own data. After all, data is the new oil. But the path will indeed be challenging, as AWS(Amazon Web Services), Azure (Microsoft), and GCP (Google) really hold a good market share and have very good communities and services to offer. Catering to the masses and providing services like serverless really requires capital and talent to build. Additionally, they have the market, so catering to the masses at a lower cost will be feasible for them. Let's see how Krutrim is going to foster; I am keenly observing the debate. PS: Gonna study the cloud unit economics next, what i feel is if server(hardware) cost the same: then potential price hike could be in: infrastructure costs, taxes, electricity, and real estate, which can vary significantly depending on the location, different for US and India, so why is the price same? Do leave your valuable comments on the same... #bhavish #krutrim #ola #cloud #aws #azure

Dhoni! The nightmare to Hotstar and Jio Cinema. At the end of this post, I have two links where the Hotstar and Jio executes tell us why Dhoni makes their life so interesting and so difficult. Don't miss to watch. The problem is traffic. Dhoni can take it to astronomical levels. One common solution to this problem is autoscaling. But... hmm... that just does not do magic. Autoscaling does not work when there are traffic spikes i.e., sudden increase in taffic. For prominent cricket matches, hotstar observes spikes of about 1M users per minute adding to the number of active users. A star batsman gets out and the traffic drops by several millions in that minute. This kind of spike is harmful for backend services. Funny problem for hostar is that if users press the back button (instead of just closing the browser), the traffic goes to home page. If homepage was configured for lesser traffic, it gets into trouble. There could be more challenges. What if AWS has no capacity (in a specific AZ) to provision servers to you? So, autoscaling does not always work. Say, you use step-wise scaling, i.e., say, 10 servers at a time with the objective to scale up to 800 from 100. This is too slow. 1 M requests per second, 10 TB of video bandwidth per second (75% of total internet bandwidth available in India) - These numbers are mind boggling! Even the ISPs can get choked delivering this kind of traffic. Streaming services face these challenges all the time. Royal wedding, IPL finals, Trump's activities, and so on. How do you prepare the platform for such spikes? Hotstar uses 3000 machines with 36 CPUs and 72GB RAM, spread across different regions, just to generate the load that hits the platform for load testing. The testing they do to face the spikes is called "Tsunami" testing. A breaking point is calculated for each service. This number is then used to decide the scale of infrastructure. How to solve this problem, then? 1) Use buffer to account for spikes.  2) Pre-warm the infrastructure. So, the uptime is low.  3) Find the right metrics on which scaling can happen "anticipating" a spike, not after a spike has happened. For example, when drinks break ends, expect high load.  4) Use a variety of EC2 instance types. This diversity (memory intesive, compute optimized, etc) can save you if the change in traffic pattern requires a specific resource type.  5) Decide which of your services are P0 and which are less important. Upfront declaration such as that would allow you to reduce resource usage on less important services (and make them available for P0 ones). For example, movie recommendation service is less important than live video delivery esp., when Dhoni is batting. Finally, I note that hotstar and Jio prepare harder for IPL finals than our cricket teams!

SDE & SDE-2 at Amazon was no easy feat😕 The biggest challenge? The intense preparation. Everyone I spoke to, from seasoned engineers to interns, all agreed - Amazon and other tech giant's interview bar is high. It's enough to make anyone question their abilities. With this, my initial excitement quickly turned into self-doubt. But through months of preparations with consistency (because without it you can't prepare) I cracked Amazon. The journey was not simple and easy with a full-time job. However, I scheduled a few hours after work for preparation—working on coding challenges and whiteboard sessions daily. I focused on areas that aligned with my target role, like development and system design. Connecting with professionals working for the same role, gave me invaluable insights into the interview process and company culture. At last Every. Single. Second. Was. Worth. It.

How Hotstar Scales their infrastructure during a cricket match. 1. Using CDNs to spread out the traffic so no single server gets overwhelmed. 2. Autoscaling their servers to handle spikes in viewers as the match heats up. 3. Using edge servers closer to users to speed up streaming. 4. Caching content so it's quickly accessible without delays. Check out this video where the Hotstar team explains how they manage it all: https://lnkd.in/duA8FDqD #WebInfrastructure #WebScaling #ContentDeliveryNetwork #CloudInfrastructure #HighTrafficWebsites #EdgeServers #WebPerformance #RealTimeMonitoring #TrafficOptimization #LoadBalancing #WebDevelopment #TechScaling #WebScalingSolutions #AWS #CloudFront #S3

🔍 Ruchir Sharma Decodes Trump's Election Victory and Its Impact on the Global Economy In his latest analysis from #BreakoutNations, renowned economist Ruchir Sharma explores the implications of Trump's recent election win. Out of 70 polls, only 20% of incumbents have secured victory, signaling a significant protest vote from the electorate. 📊 Key Insights The low incumbent win rate suggests widespread voter dissatisfaction and a desire for change. 📈 Tariffs and Executive Authority Tariffs can now be implemented via executive orders, bypassing the need for Congressional approval. This allows for quicker economic adjustments in response to global trade dynamics. 🏛️ Areas Requiring Congressional Action 💰 Fiscal Stimulus: Essential for driving economic recovery and supporting growth initiatives. ✂️ Tax Cuts: Crucial for increasing disposable income and encouraging investment. 🛂 Immigration Reform: Vital for addressing labor market needs and enhancing national security. 🌐 Geopolitical Implications If #Trump perceives a strategic advantage in negotiating a deal with China, he is likely to pursue it aggressively. This move could lead to a transactional relationship between the U.S. and China, where economic gains are prioritized over longstanding alliances. Consequently, allies may reconsider their strategic partnerships, evaluating the benefits and risks of aligning closely with the U.S. in a shifting geopolitical landscape.

Apple trumps Samsung Electronics in India even without passing #plischeme savings to domestic consumers  In the first half of 2024, the iPhone maker shipped 4.8 million units for a revenue of $4.56 billion, according to data from market tracker IDC. Samsung’s volumes in the same period were almost double, at 9.8 million, despite a 15.4% year-on-year (YoY) decline in April-June shipments. However, its revenue stood at $3.43 billion, a gap of $1.13 billion.

Working professionals while transitioning to SDE 1 or SDE 2, know the importance of System Design.💡 And my 2 years at Samsung have made me realize just that. Now, what to expect in the System Design Round? The round begins with the interviewer giving you an abstract problem, for which they expect you to ask clarifying questions. Now, to get the optimal solution: 🔹 Always make sure to be on the same page as the interviewer. 🔹Throughout the process explain your choices and discuss alternatives and their pros and cons. 🔹Discuss and make Trade-offs in your design. Lastly, make sure to have a strong grasp of Data Management. A bonus tip - Regularly practice common questions asked, if you want to understand different aspects of System Design. Follow this and make system design rounds easy to crack. Now, if doing all these things feels like too much for you take the help of industry veterans, at Bosscoder Academy.

Companies fail, founders don’t. <excerpt> Wishberg, a wishlist site launched in 2012 by Pravin Jadhav and Kulin Shah, struggled and was acquired by Freecharge in 2014, which Snapdeal bought in 2015. Jadhav was then brought on board at Paytm to start Paytm Money for stock trading, and eventually started his own, called DhanHQ. Shah worked at Acko before founding Onsurity, an employee health benefits platform. India’s internet ecosystem is full of stories of founders starting up, shutting down, being acquired, of being forced out, before they build something that works. Many founders who exit their businesses reinvest in new ventures. Freecharge’s Kunal Shah has funded over 200 startups so far. Venture capitalists also often back founders who have tried something new and failed. India’s startup ecosystem is still innovating and is in the process of maturing. As they say: companies fail, founders don’t. </excerpt> Source link in the comment.

IPL: Razorpay's Second Innings 🏏 The title "IPL: Razorpay’s second innings" really intrigued me. What does a fintech platform have to do with IPL? 🤔 It turns out, user behavior during an IPL match, like ordering food or gaming, had an indirect impact on Razorpay. In 2019, they struggled with traffic bursts during IPL matches, which lasted over 10 minutes—something their engineering hadn't anticipated. After this challenging IPL season, they strategized to handle future traffic bursts better. Here are the key problems they identified and solved: Problems: 🧵 Thread Exhaustion: PHP Laravel, their backend, lacked proper DB connection pooling, blocking threads and connections when the gateway took longer. 🚦 Throttling: They weren’t throttling requests, making them vulnerable to DDoS attacks. 🏦 Banking Gateway Backpressure: Banking gateways experienced 20x their normal P99s during traffic bursts. 🚥 Smart Routing Requests: There was no way to identify the load on different banking gateway nodes to route requests to less loaded ones. 📊 Alerts & Monitoring: Their alerting mechanism was too slow, giving them no time for remediation. Solutions: 🧵 Thread Exhaustion: They used ProxySQL as a layer between the backend and MySQL, deploying it as a sidecar with each backend pod for fault tolerance. 🚦 Throttling: Implemented simpler fixed window rate limiting instead of the earlier one which was a leaky bucket algorithm implementation backed by a Redis store, also moved this service to an NGINX-based proxy server as a side car with dedicated cache and new rate-limiting configurations (e.g., requests per route per merchant). 🏦 Easing Banking Gateway Backpressure through Smart Routing: Built a machine learning-based system to route transactions smartly, considering earlier payment success/failure events. This improved success rates by 60% during bursts and 4% during normal periods. 📊 Alerts & Monitoring: Using Victoria Metrics and Grafana, they developed a real-time alerting system for business and engineering KPIs. This is how Razorpay overcame their engineering challenges!

We Come From Two Indias One where the rich can get away with murder. The other where the poor are arrested for trivial crimes. One where a 17-year-old rich brat can ram his unregistered Porsche, killing two innocent people, and be released on bail after just 15 hours by writing an essay. The other where an ordinary citizen is arrested simply for expressing views against a political party. One where money suppresses all crimes. The other where jails are filled with hundreds of people languishing for years, despite not being found guilty by any court, and most of these are young, barely literate, and too poor to afford bail. Clearly the Indian judiciary system applies differently to the rich and poor. #puneaccident #justice #RichVsPoor #systembias
