Highlights

• - Built DataMart, an auditable Excel-to-PostgreSQL import pipeline where a dry run shares its core with the import path, behind a human review gate.
• - Ingested a 1.1-million-row, 60 MB workbook end to end, with every suite green: functional tests on real PostgreSQL, browser specs in headless Edge.
• - Authored Furrballs, a topology-aware concurrent cache measuring 22x lower p50 GET latency and 10x higher throughput than Meta CacheLib on YCSB-A, published as Technical Report v1.34.0.
• - Built and operated the Esprit Market DevOps stack end-to-end as lead of an ESPRIT team project: 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 that consolidated 4–7 rented servers onto a single internal server.
• - Built a shared library used across 12 supplier microservices: booking types, DB operations, and configuration layer (Ristretto caching, Redis/MongoDB/MSSQL pooling).
• - 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.
