I build accessible web applications that are still a pleasure to maintain five years from now. For the past eight years.
// About
About
PV
With over 8 years of experience, I build modern and interactive web applications that bring ideas to life.
My tech stack includes React, TypeScript, CSS3, HTML, Python (Django/FastAPI), Next.js, Node.js, Postgres, and Docker. I value clean code, proven design patterns, and consistent accessibility implementation (WCAG/BITV).
Regular refactoring and code optimization for maintainability come naturally to me. I use Jest or pytest for unit tests and Playwright for end-to-end testing.
