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 — MERN stack applications, DeFi platforms, AI-powered tools, Shopify themes, and B2B SaaS products. I've built MLM billing systems, defence procurement platforms, NFT dApps, and social scheduling tools. Not because I chase trends, but because clients come with real problems and I figure out how to solve them.

Outside client work, I'm a CS student at Virtual University and actively building toward my own SaaS products. I'm currently learning LangChain and LangGraph to add AI agent development to my stack — not for the resume bullet, but because I see where the market is going.

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