Pavlo K.
Next.js & TypeScript Engineer | App Rescue & Performance
I take over existing Next.js and Node.js apps - slow, half-finished, or inherited from a previous team - and get them shipping again. What I do: - Rescue & refactor - existing Next.js / React / TypeScript codebases, stuck features, tech debt - Performance - slow pages, Core Web Vitals, API latency, with before/after numbers - Backend & integrations - Node / Nest.js APIs, PostgreSQL, Strapi, AWS, webhooks, third-party services - AI features in existing apps - LLM endpoints, streaming responses, Vercel AI SDK 100% Job Success | 6+ years in production. How I work: written-first communication, honest estimates, small reviewable PRs. I read your codebase before making promises, and I measure results instead of describing them. Have a live product that needs fixing, speeding up, or extending? Send me the context - I'll tell you what I'd tackle first and why.
