Ziad Asr

I’m a backend developer with experience building scalable REST APIs, multi-tenant systems, and distributed architectures using Node.js, TypeScript, PostgreSQL, and Redis. I focus on reliability and performance through concurrency control, RBAC, and database-level correctness, and I enjoy turning complex requirements into clean, maintainable APIs.

At MySlots, Inc., I built 5+ REST APIs for a scheduling platform—covering booking logic, availability, and conflict resolution. I also collaborated with a 4-person team on backend architecture decisions and UX-facing API design.

My projects push the same mindset further: I built a full-stack e-commerce platform with JWT authentication, RBAC, and WebSocket real-time updates, and I designed a multi-tenant task system with strict data isolation and Redis pub/sub notifications. For my graduation project (expected Jul 2026), I’m applying reinforcement learning to HPC scheduling using a MARL (PPO) system trained on 25,000+ jobs from real HPC traces.
