Andrew Katsewich
Frontend Developer
Vilnius, Lithuania
I am a software engineer with 7 years of commercial experience. Through my career I contributed to more than 15 commercial projects. This includes both projects where I was working as a part of a frontend team and projects which I setup and maintained on my own. Experienced in diverse web projects, I deliver effective frontend solutions with a strong focus on product development and the end user. I prioritize lightweight, high-performance, and extensible solutions in development. I leverage AI tools such as Windsurf and GitHub Copilot for code completion and chat to enhance productivity. I am comfortable working with existing codebases and enjoy refactoring and optimizing code when opportunities arise.
