About

I am a professional web developer. For 19 years, I have worked on various tasks, including backend and frontend development, small team management, performance optimization, vector graphics and animation, test automation, deployment configuration, and more. Therefore, I understand product development from different angles. I can speak the same language with different people and quickly switch between technological stacks if needed.

I aim to write code that is easy to maintain and create a product that users enjoy interacting with. I also find it important to have smooth and effective processes, so I will likely try to participate in their improvements or automation.
