I have 12 years of commercial experience in software engineering. I work mainly in JavaScript and Python, formerly C#, and occasionally C++. I have handled a broad range of front-end and UX design topics, as well as back-end work (SSR/SSG, API proxy), database programming, and device communication.

As part of my own business activity, I successfully delivered and implemented solutions improving operations in small companies. I worked on contracts for large clients from the USA, Norway, Germany, and Poland, delivering scalable systems. In recent years I focused my professional growth on frontend technologies, with a stack centered around React. I continuously improve work organization - both my own and the whole team's - using artificial intelligence tools and CI/CD automation. I care about security, architecture, and code clarity.

As a hobby, I do photojournalism and design and program IoT devices. I play in a percussion band. I enjoy mountain trips.
