Andrew Katsewich

Full Stack Developer
Vilnius, Lithuania

I am a software engineer with 6 years of commercial experience. In development I choose lightweight and performant solutions and methods that will be extensible for future iterations. I have also adopted AI, I use the Codeium extension for both code completion and chat, it really comes in handy for some tasks. When it comes to my work, I'm used to working in teams as well as starting and maintaining projects on my own. My experience covers various types of projects and I accumulated a lot of relevant solutions to different frontend needs. I don't mind digging someone else's code and enjoy refactoring and optimizing if there's a chance. I take responsibility for product development and think about end-user.
