Looking for a production-ready MERN stack app or an AI automation that actually delivers?

Hey there! I am a full stack developer with 6+ years of experience building with ReactJS, NextJS, and NodeJS. Over the years I've shipped 150+ apps and helped scale SaaS platforms to millions of users.

Here's something I've noticed after years on Upwork: most developers are either really good at MERN stack work or really good at AI, but rarely both. I do both, which means you get one person who can build your actual product and also wire up the automation around it, instead of hiring two freelancers who end up stepping on each other's toes.

What I usually work on:
▪️ MERN stack apps: MongoDB, Express, React, Node.js, Next.js, and Python when the project calls for Django, Flask, or FastAPI, taken from a rough idea all the way to something live and production ready
▪️ APIs: REST and GraphQL builds, plus integrations with Stripe, Twilio, OpenAI, Firebase, PayPal, and OAuth logins
▪️ Scaling: MongoDB backed architecture built to handle real traffic, not just look good in a demo

Some numbers that back this up: $800K+ earned on Upwork, a 5.0 star average, 11+ apps launched including 3 SaaS platforms that crossed 500K users, and 90+ custom APIs shipped with proper caching and rate limiting so they don't fall over under load. I'm also a certified MERN Stack Web Developer through IEMLabs.

I've worked across fintech, healthcare, real estate, and e-commerce, industries where clients care more about whether the code actually holds up than whether it looks nice in a demo call.

If you've got an idea and a rough timeline, send it over. I'll reply within 24 hours with an honest execution plan and cost breakdown so you know exactly what you're getting into.
