About Me

Senior Frontend Engineer with 8 years of experience in software development and mentoring, focused on building reliable, high-performance, and accessible web applications.

I participate in the full development lifecycle - from requirements definition to release, CI/CD pipeline configuration, and ongoing support. I have experience working in distributed teams of 5–10 people and leading a cross-functional team of up to 5 members.

My most recent open-source contribution is kapi.bar, a social network built with Vue.js on the frontend and Python on the backend, where I focused on improving frontend architecture and overall user experience.
