Full-Stack MERN DeveloperWeb3 & BlockchainAI IntegrationsOpen to Remote Work

I write code that gets used by real people, for real businesses.

I'm Umair — a full-stack developer based in Pakistan with 4+ years building production apps. I currently work at Decrypted Labs, a Web3 and AI development company, where I handle everything from Next.js frontends to blockchain integrations to deploying on DigitalOcean.

My work spans a pretty wide range, but a pattern keeps showing up: someone is running a real business on spreadsheets, radio calls or a paper form, and needs it turned into software that doesn't fall over. I've built dispatch software a towing company runs its daily jobs on, fiat and on-chain payment rails for an MLM platform, RWA tokenization contracts across three different blockchains, and practice management CRMs for two separate healthcare businesses.

On the AI side, I'm past the tutorial stage — I've shipped a RAG chat widget that reads a website's own content and answers visitor questions from it, and I use LangChain and LangGraph for agent work day to day, not as something I'm still learning. Outside client work, I'm a CS student at Virtual University and I'm building toward my own SaaS products in whatever time is left over.

If you need someone who can scope a project, build it, debug it, and deploy it without hand-holding — I'm the person.
