RESUME
Hamza J. Saied
Backend and systems engineer with production experience across C++20 concurrency libraries, Go/gRPC services, and Kubernetes-based DevOps. Focus on performance, low-level design, and production reliability.
Highlights
- - Built and operated the Esprit Market DevOps stack end-to-end: kubeadm Kubernetes with Kustomize, Jenkins CI/CD with Trivy scanning, Prometheus/Grafana monitoring, and VPS bootstrap automation.
- - Owned the SRV module and most Common shared foundations (JWT auth, RBAC, real-time messaging) in a team Java/Spring Boot backend.
- - Contributed to a Go/gRPC migration consolidating 4–7 rented servers into a single internal server, eliminating recurring hosting costs.
- - Built a shared library used across 12 supplier microservices: booking types, DB operations, and configuration layer (Ristretto caching, Redis/MongoDB/MSSQL pooling).
- - Authored Furrballs, a NUMA-aware concurrent cache benchmarked at 19× the throughput of Meta CacheLib on EC2 c6a.metal (14.3M vs 740K ops/s).
- - Implemented production room-packing and booking-lifecycle consistency checks across supplier flows.
- - Selected to represent the class at Bal des Projets (ESPRIT showcase, ~250 projects); shortlisted for incubator — 1 of 25.
