I'm Saad, a full-stack AI engineer based in Pakistan. I design the backend infrastructure agents need to run reliably (auth, permissions, data layers) and the agent logic itself: tool-calling loops, multi-provider routing, context management, and the guardrails that keep autonomous systems from going off the rails. Currently a CS undergraduate at the University of Sargodha, graduating June 2027.
