About Hassan Javed

I'm Hassan Javed — a Senior Full-Stack & Blockchain Engineer based in Pakistan. For the past 6+ years I've been shipping production-grade MERN-stack applications, React & Next.js platforms, React Native mobile apps, Node.js APIs, Solidity smart contracts, and AI automation systems for clients across the world.

I started as a full-stack web developer on freelance platforms (Upwork, Fiverr) and gradually moved deeper — first into the MERN stack, then into Solidity and Web3 when the DeFi wave hit, and now into AI agent orchestration with N8N, OpenAI, and Claude. Each layer has been an additive choice: I haven't traded one stack for another, I've compounded them.

Today I lead engineering work that spans token launchpads, staking platforms, NFT marketplaces, DeFi primitives, cross-platform React Native apps shipped to the App Store and Play Store, and AI-driven workflow tools. Along the way I reduced one team's deployment time by 50% through CI/CD overhauls and automation.

In late 2026 I founded Up24 Solutions, an agency building business software for Pakistani SMBs — point-of-sale, hospital and management systems — where I lead engineering and delivery. This site stays about my own work: senior contract and Web3 engineering, taken on directly.

My engineering philosophy is simple: ship things that survive contact with real users and real money. That means audited code, sensible test coverage, observable systems, and documentation that the next engineer can actually use. I'm allergic to demoware.
