Backend systems
APIs, microservices, async pipelines — reliability over cleverness
Senior Software Engineer·Islamabad, PK
Umar Hassan Khan.
I build backend systems, cloud infrastructure, and full-stack applications. Primarily backend and cloud native — full-stack across the product when needed. Whatever domain the problem lives in.
Cloud-native infra
AWS, Docker, IaC, CI/CD — infra that lives in a repo, not in someone's head
Full-stack apps
Responsive Web apps, hybrid mobile when the product needs it
Auth & identity
WebAuthn, OIDC, OAuth2, W3C VCs — a domain I'm drawn to
AI & Agents
Multi-agent systems, RAG, agentic copilots
Web3
Stellar, Cardano, EVM chains, Wallets, dApps, on-chain integrations
