You will get a full-stack MVP web app built in Next.js and NestJS
Project details
Got an idea but no product yet? I turn it into a working MVP you can put in front of real users — fast, clean, and built to grow. Full-stack: Next.js frontend, NestJS + PostgreSQL backend, auth, payments, and deployment, all done for you.
6+ years building production web apps end to end, including the platform behind a brand now at ~$4M in revenue. I think like a product engineer: we agree on the smallest version that proves the idea, then I build it properly — no throwaway code you'll have to rip out later.
You get a real, deployed app (not a prototype), clean TypeScript your future team can extend, and weekly demos so you always see progress. Auth, Stripe payments, dashboards, admin panels — whatever your v1 needs.
Send a short brief of your idea — I'll reply with a scoped first step and a realistic timeline. Bigger build? Go with the Multi-Feature MVP or Full MVP + Payments tier.

About Serdar
Senior Frontend & Full-Stack Developer | React, Next.js & Stripe
Mary, Turkmenistan - 6:06 am local time
6 years shipping production web apps — including the e-commerce platform behind Unidea, a brand now at ~$4M revenue.
🚀 6+ years building production web apps end to end
🛒 Built the platform behind Unidea (unidea.ru) — a custom-product brand that scaled to ~$4M (₽382M) revenue, +5.2x YoY
💳 Stripe payments — deposits, full-payment, 3DS, multi-currency, error recovery
📈 +15% checkout conversion · −35% critical bugs · +25% faster delivery (last product)
🧩 Full-stack: React/Next.js front + NestJS/Prisma/PostgreSQL back, self-hosted deploy
👥 Led & mentored frontend teams (grew a team 1 → 3, mentored 4 devs)
🔥 WHAT I DO
You're building a web product, MVP, or SaaS that needs a frontend that converts and a backend that holds up. I own it end to end — React/Next.js UI, NestJS APIs, PostgreSQL, payments, and deployment — and ship in weeks, with clean code your future team won't curse.
🔥 WHAT I BUILD
✅ Frontends that convert — multi-step onboarding, pricing & checkout, dashboards, admin panels
✅ Backends that scale — NestJS REST APIs, PostgreSQL + Prisma, Redis queues, JWT/argon2 auth
✅ Stripe billing & checkout — deposits, full-payment, subscriptions, 3DS, multi-currency
✅ Next.js apps — App Router, SSR / SSG, SEO, Core Web Vitals
✅ Quality built in — Playwright E2E, TypeScript strict, Zod validation, Swagger API docs
✅ Ship & run it — Docker, self-hosted deploy (Coolify on Ubuntu/VPS), AWS S3, CI/CD
🔥 RESULTS I'VE DELIVERED
✔ Built the e-commerce platform behind Unidea (unidea.ru) — a custom-product brand now at ~$4M (₽382M) revenue, +5.2x YoY
✔ +15% offer-to-checkout conversion on a 7-step booking funnel
✔ −35% critical regressions with Playwright E2E coverage
✔ +25% faster feature delivery using AI-assisted workflows (Claude, Codex)
✔ Shipped full-stack apps end to end — React/Next.js front, NestJS/PostgreSQL back, self-hosted deploy
🔥 HOW I WORK
I think like a product engineer, not a ticket-taker. I align on the business outcome first — who the user is and what they pay for — then ship in weekly demos with clear, written updates (async-friendly and comfortable across time zones).
1️⃣ Discovery & scope — define the MVP boundary
2️⃣ Architecture — clean, scalable foundations (FSD + TypeScript)
3️⃣ Weekly sprints with demos
4️⃣ Launch — CI/CD, tests, monitoring
5️⃣ Post-launch support
