Introduction
Senior Oracle DBA with 14+ years of experience, now based in Maisons-Laffitte (Île-de-France) and actively seeking my next Oracle DBA / GoldenGate opportunity in the Paris region. Most recently a Principal Advanced Service Engineer at Oracle, where I specialized in Oracle GoldenGate 23ai Microservices Architecture, RAC, Data Guard, and Exadata performance tuning. I have deep expertise designing and deploying real-time data replication systems and multi-cloud architectures spanning OCI, Azure, and Kafka. Track record of leading database replication, migration, and optimization projects for enterprise clients. Skilled in using AWR and ADDM for performance tuning, executing Oracle Enterprise Manager upgrades, and automating database administration tasks. Passionate about delivering high availability, disaster recovery, and robust cloud-based solutions to support critical business operations. Open to CDI or freelance/mission roles, on-site or hybrid, anywhere in France. Happy to connect with recruiters and hiring managers.
