Über mich
Senior frontend developer with 8+ years of commercial experience. I build and maintain production web apps with React, Next.js, TypeScript, Vue, Nuxt, Astro and Nest.js.
What I do best: fixing tricky frontend bugs, speeding up slow pages and improving Core Web Vitals, refactoring messy codebases, and turning designs into pixel-accurate responsive interfaces.
You get clean, typed, maintainable code, a clear explanation of what I changed and why, honest estimates and fast replies. Available for both small one-off fixes and ongoing part-time work.
