About

Hi, I’m Malak Joumaa, a Senior Full Stack Engineer from Lebanon. I’ve progressed from a Junior to a Lead role at a fast-scaling European SaaS company, where I design architectures, steer sprint delivery, and champion code quality across a multi-tenant reporting platform.

I’m actively exploring AI agentic engineering in parallel, building production-ready features with Claude Code conductor and MCPs, while mentoring teammates and expanding my stack with React, TypeScript, GraphQL, PostgreSQL, and AWS.
