About
I build production systems where backend, AI, and product decisions meet.
I am Bilal Sharif, a full-stack engineer based in Lahore, Pakistan. My work is mostly Python, Django, FastAPI, React, PostgreSQL, Redis, WebSockets, applied AI, and security-aware automation.
Positioning
"The best engineering work is not just writing code. It is knowing which bottleneck matters, what should stay simple, and where the system can break under pressure."
I have worked across production backends, multi-tenant SaaS, 20K-connection WebSocket workloads, RAG pipelines, AI agents, document conversion, ML workflows, protocol reverse engineering, and Django security auditing.
I also use AI-assisted tooling as part of the delivery workflow: Cursor, Claude, Codex, and Copilot. The goal is faster execution without lowering engineering judgment.
