Hire Ruby on Rails developers

I didn’t start out as a developer. I was just someone who got tired of repeating the same tasks over and over. One day, I decided to automate a spreadsheet for my side project, it took me a week, broke three times, and barely worked. But when it did work, it felt like magic. That moment sent me down the rabbit hole. I learned HTML and CSS to make things look alive, then JavaScript to make them do something, then backend code so they could remember. Now, I build systems that save people hours, sometimes days, of work. It started with frustration. It became curiosity. Now it’s my craft.

As a backend developer with a strong foundation in both science and technology, I offer a unique combination of academic research experience and hands-on software engineering expertise. I hold a master’s degree from the Moscow Institute of Physics and Technology and spent seven years at the Institute for Nuclear Research in Troitsk, contributing to the Baikal Neutrino Telescope project. This background sharpened my analytical thinking and problem-solving skills in high-complexity environments. Alongside my research, I built a solid foundation in software development, working with C++, PHP, and bash. Eventually, I transitioned fully into tech, taking on roles as a Network and Software Engineer before progressing to Senior Software Engineer and Team Lead positions at Qlean. I’m currently based in Berlin, Germany, working as a Senior Backend Developer at Handshake. My primary language is Ruby, but I’m also interested in Golang, Rust, and Elixir. I thrive on solving complex technical challenges, writing clean and scalable code, and continuously learning new systems, algorithms, and techniques. At the same time, I understand the importance of balancing technical ideals with business realities — sometimes, delivering a valuable feature on time is more important than writing perfect code. Looking ahead, I’m excited to connect with like-minded professionals, explore new challenges, and continue building reliable, impactful software.
