You will get your React or Next.js bug fixed fast, clean and tested
Project details
Got a React or Next.js bug that's slowing you down? I'll find it, fix it cleanly, and make sure it stays fixed — without breaking the rest of your app.
I'm a senior frontend & full-stack developer with 6+ years in production React/Next.js apps, including the platform behind a brand now at ~$4M in revenue. I've worked through the real stuff: state bugs, broken builds, hydration errors, API and Stripe issues, layout and responsiveness problems, and performance regressions.
What you get: a clear diagnosis of the root cause (not just a patch), a clean, tested fix, and a short note on what caused it so it doesn't come back. I write clean TypeScript, work fast, and keep you updated in plain language.
Send the bug, your repo or a zip, and steps to reproduce — I'll reply with a clear first step. Bigger issue or a small feature? Go with the Multi-Fix or Fix + Feature tier.

About Serdar
Next.js & NestJS Developer - SaaS MVPs with Stripe Billing
Dubai, United Arab Emirates - 5:28 pm local time
I've got six years of commercial experience under my belt. Frontend: React, Next.js, TypeScript. Backend when needed: Node.js and NestJS.
🚀 Recent results:
✅ Built a 7-step booking funnel for a travel startup (Next.js, Stripe with 3DS). Offer-to-checkout conversion grew by about 15%.
✅ Set up Playwright E2E tests and an analytics layer (GTM + Amplitude). Critical regressions dropped by about 35%.
✅ Migrated a product from React to Next.js with clean architecture. New features now ship about 30% faster.
🤝 How I work:
💬 Daily updates, short and clear.
📋 Honest estimate before I start. If something changes, you hear it from me first.
🧹 Clean TypeScript code the next developer can read without pain.
🛠️ I take frontend projects (React, Next.js) and full-stack JavaScript projects (React + NestJS): new builds, features in existing products, bug fixes, performance work, REST APIs.
