Two Years at Intellias: A Reflection Time flies, and it’s hard to believe that two years have already passed since I joined Intellias. As I look back, I realize that these have been the most productive and intense years of my professional life. Let me share my journey, divided into three main stages: 1. MBD/MBSD (MATLAB/Simulink) Stage My journey began with developing the Model-Based Design (MBD) and Model-Based Software Development (MBSD) direction within our company. While I had learned MATLAB/Simulink during my university years, it was at Intellias that I truly delved into its power. Together with my colleagues Dmytro Humennyi, Ph.D., Davor Antonic, Pooja Gupta, and Artem Yaroshevskyi we worked on several AUTOSAR and non-AUTOSAR projects, leveraging MATLAB/Simulink, AUTOSAR Bockset, and Embedded Coder. We even developed a basic operating system for an internal training program with the use of the Arduino boards and the Arduino Framework. We also managed to port the same software component to the POSIX platform. The challenge was to make it real-time, and we succeeded! 2. SW Architectural Stage I then transitioned to the role of Software Architect on a three-phase Electric Motor Control Unit project. Managing the entire software stack for the Application partition, including the startup code, Flash Bootloader (FBL), and Hardware Security Module (HSM), demanded both technical prowess and an understanding of mechanics and electro-mechanics. I’m grateful for the support from Karoly Ferencz and Abdelrahman MABROUK on this stage. 3. Functional Safety Stage Finally, I took on the role of Project Safety Manager for a Firmware Over-the-Air (FOTA) Master Application. This was a significant challenge for me, as I had worked on Safety Projects before but never as a Project Safety Manager.  With the support of  José Antonio Gómez Requena and Dhanabal Arunachalam I managed this challenge. Functional Safety became more than just reports. It shaped my entire approach to work. Building an Electrical SDV Alongside these stages, our team worked on internal projects. One notable achievement was building a simple Electrical Software-Defined Vehicle (SDV). Our SDV sample included Electrical Engine Control Units (EECUs), an Interior Light Control Unit, a Zone Gateway (Zone Controller), and a High-Performance Computer (HPC) based on Raspberry Pi. We designed communication from EECUs to ZoneGW via CAN, then ZoneGW to HPC via Ethernet and SOME/IP. The GUI interface on the HPC side allowed users to control vehicle speed and interior lighting. After a software update, our SDV featured Dynamic Light Control based on vehicle speed calculated from RPM values from each EECU. Acknowledgments I want to express my deep gratitude to the entire team, our managers Oleksandr Odukha, Volodymyr Mandzyuk, Oleksandr Nazarov, Sergii Shcherbakov, Adam Konopa and everyone who made these projects possible. It’s the collective effort that drives success.

Hello! I'm now in my seventh week of actively seeking a new role, and I'd like to share some observations from my journey in the IT job market: Market Dynamics: Contrary to common beliefs, the IT market isn't as bleak as some suggest, nor as idyllic as it once was. The bubble has indeed burst, leading to a more refined market. Options may be fewer, but demand for highly skilled professionals remains strong. I find it particularly engaging when asked about my achievements in previous projects during interviews—it’s both challenging and exciting. Salary Transparency: Salaries are competitive and often transparent. Most job openings now provide a clear salary range, reflecting a maturation in the job market compared to years past. Recruiter Efficiency: The jokes about recruiters couldn’t be further from the truth! Most recruiters are knowledgeable and precise, with only rare technical misunderstandings—perfectly understandable. Technical Interviews: While they can be intense, they are not the nightmares they’re made out to be. Most interviewers are friendly and trusting, focusing on your actual skills and knowledge, though make no mistake - you will be tested and tried. Feedback Culture: More than half of my job applications receive a personalized response—excluding autoresponders. The further I get in the application process, the more detailed the feedback becomes. I am quite pleased with the level of detail provided as I progress deeper into the process. For those also navigating the IT job market, here are two tips: Diversify Your Search: Explore various job boards. I've found LinkedIn, Just Join IT, and No Fluff Jobs to be particularly helpful. I tried a few other boards but with little results. Smart CV Building: Focus not just on aesthetics but on substance. Clearly articulate what you truly excel at; your resume should serve as a blueprint of your expertise, setting the stage for your interviews. If you have tips or experiences to share, I’d love to hear them! #OpenToWork #ITJobs #JobSearchTips #JobHunt

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]

We had a discussion with Maks Kaplunov, our head of the iOS and Android teams about common mistakes developers make when building iOS apps and gathered valuable information: tips on how to prevent and fix them!🔥🔥🔥 📌Save this for future reference! 1. Ignoring Error Handling    - Mistake: Many developers ignore errors or use `try!`, which can lead to unexpected app crashes.    - Tip: Always handle errors with `do-catch`, and when necessary, inform the user about the issue to ensure the app remains stable. 2. Memory Leaks    - Mistake: Incorrect use of closures or strong references can cause memory leaks and degrade performance.    - Tip: Use weak or unowned references where needed, and test the app with tools like Xcode Instruments (Leaks, Allocations, Zombies). 3. Improper Multithreading Management    - Mistake: Poor organization of multithreading, performing heavy operations, and network requests on the main thread can cause the interface to freeze or lock up.    - Tip: Delegate heavy tasks to a background thread, ensuring that UI updates occur on the main thread. Review different approaches to multithreading, such as GCD, Operation Queue, and async/await, as they each have advantages and should be used appropriately. 4. Unoptimized Resources and Assets    - Mistake: Using unoptimized images and resources can increase the app size and slow down loading times.    - Tip: Optimize images using formats like HEIF/HEVC, and use tools like ImageOptim to compress files without quality loss or opt for SVG formats. Also, avoid resource duplication. 🚨More tips to come in the next post!
