About this gig
Is your custom website or SaaS app stuck a slow build, a broken backend, or an AI / vibe-coded app that demos fine but breaks with real users? I fix that and ship the real thing.
I'm a full stack developer and react developer who lives in the MERN stack (MongoDB, Express, React, Node). As a mern stack developer I build fast, scalable custom website and web application projects from scratch or rescue ones that got stuck.
What I build:
Custom website & landing pages (React, fully responsive)
Full-stack web application & SaaS dashboards
Secure login, user roles & admin panels
REST APIs & database design
Stripe payments & subscription billing
AI / LLM features & chatbots
Stack: React, Node, Express, MongoDB, Next.js, Tailwind, Stripe, cloud deploy.
Why me:
You own 100% of the source code
Milestone demos you always see progress
14 days of free bug fixes after delivery
Clean, documented, scalable code
Fast, honest communication
Message me before ordering with your idea and I'll reply with a clear scope, timeline and price.

FAQ
Do you work with the MERN stack and React?
Yes — MongoDB, Express, React and Node are my core stack. I build custom website and web application projects end to end, front end and back end.
Can you fix an AI-built or "vibe-coded" app that's stuck in demo mode?
Absolutely. Bring your Lovable / Bolt / Cursor / v0 project and I'll turn it into a stable, scalable app with a real backend, database and auth.
Can you build a SaaS app with login and Stripe payments?
Yes. Full SaaS MVPs are my Premium package — user accounts, dashboards, subscription billing with Stripe, and an admin panel.
Can you convert my Figma or PSD design into a React website?
Yes — I turn Figma/PSD/XD designs into pixel-accurate, responsive React front ends.
Do I own the source code?
100%. You get the full, documented source code and deployment on delivery — no lock-in.
Can you add AI or a chatbot to my existing website?
Yes. I add AI / LLM features, chatbots and API integrations to existing sites and web apps.
I'm not sure which package I need — what should I do?
Message me first with your idea. I'll scope it for free and recommend the right package, timeline and price before you order.
