About this gig

Hi! I'm a full-stack developer with 5+ years of experience building production-ready web apps using React, Next.js, Node.js and PostgreSQL/MySQL.


I specialize in SaaS platforms, dashboards and custom web apps from scratch. Clean, scalable and ready to ship.


What I build for you:

Frontend (React / Next.js):

  • SSR, SSG, routing, hooks, Redux/Zustand
  • Responsive UI with Tailwind CSS or Bootstrap
  • Figma / PSD to pixel-perfect frontend

Backend (Node.js / NestJS):

  • REST API design and development
  • JWT auth and role-based access control
  • PostgreSQL, MongoDB or MySQL setup and optimization
  • Payment and third-party API integrations

Full-stack and SaaS:

  • Multi-tenant architecture and admin dashboards
  • MercadoPago, Stripe and payment gateways
  • AI integrations (OpenAI, Gemini, etc)
  • Deploy on VPS, Vercel or Railway


Why work with me:

  • Built and launched my own SaaS product in production
  • Clean, documented and maintainable code
  • Fast communication and daily updates
  • 100% satisfaction guarantee


Message me before ordering so we can scope your project properly.
