As we have a lot of new internships to offer in Vention, I decided to ask Anton Niakrasau, our Department Manager who is looking for Python, .NET, Ruby, and Azure DevOps interns, what is the most important skill trainee should have. 👉 Look at his answer: “In my opinion, the core skill that trainees should have is motivation. We don't expect a lot of knowledge, but we need them to learn a lot in a short period. They need that internal drive to push themselves to work hard. This motivation will help them move forward in the future, and it is something we cannot instill in them directly – it is what we expect them to have. The next essential skill is discipline because they need the internal power to work consistently. There are times when we have to develop something not very interesting and inspiring. Even if you start your startup, sooner or later, you will have to fix bugs and write internationalization code. Another important skill we expect is proficiency in English. When people have good English skills, we can avoid the initial headache of helping them prepare for their first interview with a client😊. Speaking of hard skills, I believe they will be able to gain them while learning. However, some prior knowledge can indicate a person's diligence and hard work because it shows they did something before joining us. We have a good example that demonstrates this approach works. In 2022, we decided to help a group of people find new jobs and organized a laboratory. We did not interview any of them. As a result, we had a team where most were completely inexperienced. But by the end, they all knew how to develop applications, and eight out of ten found jobs. Their motivation and diligence, not their hard skills, helped them, and they continued working in different companies.” This couldn’t be more inspiring! All our internships here: https://lnkd.in/eW-gCn4d Apply now and kickstart your career today! 🚀 #internship #intern #hiring #net #engineer #ruby #developer #devops #python

Soon, on May 8th, we're gathering at WarsawJS Meetup #114, which will take place at the Packhelp headquarters. We've prepared a truly exceptional agenda for you with three incredibly interesting lectures! 🚀 👨‍🏫 Tomasz Ducin — Back in the game: Recent Revolutionary Changes in Angular 👨‍🏫 📝 Description: Angular has been perceived as a rather complex framework by some, yet it's used massively by enterprise-scale systems. Whether we agree with the criticism or not, the framework is undergoing a monumental transformation. In recent months, Angular is experiencing a period of frequent and significant updates and - at least considering previous years of stagnation - groundbreaking changes. These include not only the features, public API and architecture, but also to the mental models that developers come up with. 👨‍🏫 Michał Trojanowski — Securing Single Page Applications Using The Token Handler Pattern 👨‍🏫 📝 Description: Single Page Applications appear simple at first sight. Web developers provide a superb user experience, and it is also relatively easy to implement token-based security in the browser. Yet this is against current best practices for browser-based apps, and security concerns can become a blocking issue. It is instead recommended to implement a Backend for Frontend (BFF), to reduce browser threats. Yet this often results in the adoption of website technologies to issue secure cookies, which can work against other web architecture goals. In this talk, I will show how a separation of web and API concerns can give you the best choices. In the talk, I will present the Token Handler pattern — Curity's variation of the Backend For Frontend approach. I will show the open-source projects we created to facilitate the implementation of the pattern. 👨‍🏫 Tobiasz Ciesielski — TailwindCSS - Why you should have it in your project? 👨‍🏫 📝 Description: Tailwind has become the most popular styling framework. More than 8 million downloads per week via npm. Why has it become so popular? What are its advantages and disadvantages? Why did we decide to migrate to tailwind in Prowly? What are the good and bad practices of using the framework? I will answer all these questions. These lectures are not only a great opportunity to gain new knowledge but also to meet other technology enthusiasts! Don't miss out on this event! 😉 Tickets are already available, so don't wait and reserve your spot now! 👇 🔖 Tickets: https://lnkd.in/dhXVXwpf See you at WarsawJS Meetup #114! 💫 #WarsawJS #Meetup #Programming #JavaScript

Geeknauts switches to Apropo for their project estimates! 👏 👏 👏 ➡ Geeknauts, a custom software development company based in Krakow, Poland, can be definitely counted among t͟o͟p͟ 5͟ ͟#S͟a͟a͟S͟ ͟s͟p͟e͟c͟i͟a͟l͟i͟z͟e͟d͟ ͟d͟e͟v͟e͟l͟o͟p͟m͟e͟n͟t͟ ͟c͟o͟m͟p͟a͟n͟i͟e͟s͟ ͟i͟n͟ ͟P͟o͟l͟a͟n͟d͟. They know very well all the different aspects of #SaaS business - both technical and business. ➡ What I however like the most about them, is their strive for perfection. They are not satisfied with solutions that are “𝘨𝘰𝘰𝘥-𝘦𝘯𝘰𝘶𝘨𝘩”. 🔶 That’s one of the few things that I always find common for all the A-Performers - they N͟E͟V͟E͟R͟ tolerate mediocrity. And that’s the main reason why Geeknauts switched from Google Spreadsheets to Apropo - they didn’t agree for mediocrity in their estimates and proposals. 📣 Here’s what Borys Z., Frontend Developer & Sales Representative at Geeknatus, says about the impact from implementing Apropo: “Apropo 𝘀𝗶𝗴𝗻𝗶𝗳𝗶𝗰𝗮𝗻𝘁𝗹𝘆 𝗶𝗻𝗰𝗿𝗲𝗮𝘀𝗲𝗱 𝗼𝘂𝗿 𝗰𝗵𝗮𝗻𝗰𝗲𝘀 𝗼𝗳 𝘄𝗶𝗻𝗻𝗶𝗻𝗴 𝗺𝗼𝗿𝗲 𝗽𝗿𝗼𝗷𝗲𝗰𝘁𝘀 thanks to creating estimates that look 𝘄𝗮𝘆 𝗯𝗲𝘁𝘁𝗲𝗿 than Google Spreadsheets. The way how estimates done in Apropo look also massively helped with communication with our clients and 𝗯𝘂𝗶𝗹𝗱𝗶𝗻𝗴 𝘁𝗵𝗲𝗶𝗿 𝘁𝗿𝘂𝘀𝘁. Our 𝗲𝘀𝘁𝗶𝗺𝗮𝘁𝗲𝘀 𝗮𝗹𝘀𝗼 𝗴𝗼𝘁 𝗺𝗼𝗿𝗲 𝗮𝗰𝗰𝘂𝗿𝗮𝘁𝗲 which further helped us increase the profitability of our projects” 🤝 Thank you Borys and Geeknauts Crew - it’s a pleasure to have such A-Players like yourselves as our users. We wish you tons of time saved, accuracy increase and deals won with Apropo!

It was great time! 🚀 Summarizing the presentations I attended: We need to focus on the need that should be met. Not just writing code for the sake of writing code or closing a task in Jira. "(...) You wrote very good, useless code." And to recognize this need, we should emphasize communication and the way we communicate. "What's in blue, we should say in purple". Pragmatism and simplicity => simple code => less headache, lower entry barrier for new developers, simpler and more enjoyable life. The code won't call you at 3 AM, but a colleague who doesn't understand it (in a crisis situation) might. Finally, I'll quote something that appeared at the end of Mariusz Gil's presentation, which I think sums it up nicely: "In pure architecture the smallest detail should have a meaning or serve a purpose" ~ A. W. N. Pugin (1812-1852) From my self I could add to this quote " And yes, I’m talking about you, fourth abstraction layer, that is 'necessary' for making a database query." #CraftIT Michał Bartyzel Dawid Pereira

Quick engineering salary comparison based on the #DEVBG stats from 2023 and 2024 in the Bulgarian IT industry. Dev.bg publish yearly a summary of the Bulgarian IT engineering salaries based on the job openings offers on their platform. https://lnkd.in/dNU5MD8D (2023 stats) https://lnkd.in/dX_dxvP7 (2024 stats) Based on the population data (let's assume it's a proper representation of the real world) we can determine the following: 1. PHP should be dead but it isn't (unfortunately) as it's one of the two categories with growing salaries in all job positions and ranges. 2. The second is the full stack development with a minimum drop of 65 levas in the first MID range(2-5 years) 3. All ranges except the Senior level(5+ years of experience) have a drop in salary compared to 2023 but for some seem negligible compared to the notion in the industry that "it's going down and AI will take over the world" :) 4. We can see that seniority still counts and there is now a shift towards growth of salaries of more senior people compared to others as the market tries to regulate. 5. There is still a lot of green for a "dying" and "shrinking" industry. P.S To anyone interested I can share the excel if needed but it's quite straightforward to generate it. *Legend: Diff min Mid - difference in the minimum ranges for a category between 2023 and 2024 Diff max Mid - difference in the maximum ranges for a category between 2023 and 2024 Diff min Sen - difference in the minimum ranges for a category between 2023 and 2024 Diff max Sen - difference in the maximum ranges for a category between 2023 and 2024 Diff min Sen Median - difference in the minimum ranges based on the provided median from dev.bg for a category between 2023 and 2024 Diff max Sen Median - difference in the maximum ranges based on the provided median from dev.bg for a category between 2023 and 2024

So much for the basement-dwelling programmer stereotype 😉. Conferences like the International PHP Conference are splendid opportunities to gain new perspectives - and face new challenges. 🛠️ Programming is essentially about solving problems, and events just like this conference allow us to share experiences and learn from best of the best in the industry. During sessions and workshops, I got to hear real stories about real problems - how they arise, how to solve them - and how to prevent them from reoccurring. 😉 I had the pleasure of attending talks on the latest trends in PHP, code optimization and best practices in system architecture. I learned how to avoid common mistakes and what techniques to use to make our applications even more efficient and secure. 🖥️🔐 Meeting other specialists - once again - proved that exchanging insights is the key to growth. I'm glad I could be part of this inspiring community! 🤝✨ Thank you to all the speakers and participants for the incredible knowledge and motivation! 🙏📚 Topics covered: - PHP Core & Optimization [Bohuslav Šimek, Carsten Windler] - Refactoring [Ralf Eggert] - Testing, Test Driven Development, and Logging [Florian Engelhardt] - Software Architecture & Design Driven Development [Katy Ereira, Dr. Sönke J. Magnussen] - Security 🔒 - DevOps & Deployment [Nic Wortel] - Clean Code [Ondřej Mirtes] - Git Advanced & Working with abandoned Open Source Projects [Juliette Reinders Folmer]

📣 Presenting the full agenda for WarsawJS Meetup #117! 📣 The event will take place on August 14th at the fantastic BEC Poland headquarters. Check out what we have prepared for you: ► Robert Pasiński — Deep Dive into JS task scheduling We’ll go deep into what are tasks in JavaScript context, what is the difference between micro-task and macro-task, when they are run and how they are scheduled. I’m gonna go through the APIs like requestIdleCallback, requestAnimationFrame, and other that allow us to leverage the scheduling mechanism and highlight the bottlenecks. You can also expect a glimpse of how these are implemented under the hood in JS engines. ► Inez Okulska, — RAG vs GPTs fine-tuning - who wins? Natural language interfaces for information retrieval are very appealing. Hence, the popularity of GPTs for quick fine-tuning of GPT models. Are they reliable enough, though? When and why do we need more complex solutions like RAG systems? We’ll analyze this using the hAI Magazine case study. ► Jerzy N. — How to build real-time video processing web app Do you want to create a real-time video processing application? That's excellent, but have you considered how to handle delays, video compression, and high infrastructure costs? At ShareTheBoard, we thoroughly analyzed these challenges, tested various approaches, and ultimately succeeded in developing a web application that allows you to share digitized data with remote meeting participants. In this session, we will discuss the biggest challenges we faced and describe our final architecture. Join us to listen to experts in their fields and learn more about JavaScript, GPTs, and real-time video processing. It’s a great opportunity to gain new knowledge and make valuable connections! 🧠👥 🎟️ Tickets available here: https://lnkd.in/dtZmKC5G We can't wait to see you at WarsawJS Meetup #117! 🫂🤝 #WarsawJS #Meetup #TechEvents #WebDevelopment
