tl;dr

About

Software engineer with 9+ years of experience in fintech (Qonto), the travel industry (Kiwi.com) and marketplaces (GainWagon and Seasy). I am passionate about web apps, CI/CD, AI and want to learn iOS development. I greatly value educating others, sometimes contribute to open source projects, enjoy talking at tech conferences and occasionally writing articles. Master's degree in Management of software systems and services, my diploma was about AB testing.

Values

My entire career revolves around finding simple solutions to complex problems. I believe that any business requirement can be delivered while improving maintainability and performance. Quality goes hand in hand with speed and my workflow reflects that. I am a strong advocate of CI/CD and iterative development.

You can expect me to be brutally honest, transparent and to the point — I want the same from you. I want raw, uncensored feedback so that I can continually improve. I work to deliver value to the business and to the users. No redundant ceremonies, lengthy meetings or useless politics.
