About

The engineer behind the six lenses

I’m Usman Ahsan, a software engineer based in Islamabad–Rawalpindi, Pakistan (UTC+5). Over 4+ years I’ve worked across full-stack web development, AI application engineering, DevOps & cloud, blockchain/Web3, and — currently — real-time flight-simulation software at FSDC AeroSolutions. I hold a BS in Electrical & Electronics Engineering from FAST-NUCES and a Web 3.0 & Metaverse Developer certification from Panaverse, and I’ve delivered for clients across the US, UK, Gulf and Pakistan.

This site is organized as six focused portfolios — each a self-contained case for a different audience. Pick the lens that matches what you’re hiring for, or reach out directly.

Solidity engineer who actually shipped on-chain: a real Ethereum counterfeit-product-detection system (smart contracts + encrypted QR), plus security-first, Foundry-tested contracts and full-stack dApp UX on Layer-2 — public proof over credentials.
