Forward deployed engineer in Beirut. I build LLM agents and durable workflows, mostly in Python and C#, and I spend a fair amount of time in other people's codebases fixing what I run into.

MSc in Computer Science, AUB.

• Customer-facing LLM agents and the integration work around them
• Durable workflows: Temporal, retries, human approval steps, evaluation gates in CI
• Small fixes to the libraries I depend on
