Jitin in a few words
Hi, I'm Jitin — an Oracle-certified professional with 16+ years of hands-on experience in database architecture, cloud migrations, and enterprise-level performance optimization. I’ve led critical projects for global clients, ranging from zero-downtime migrations to designing high-availability architectures using Exadata and ZDLRA.
Whether it’s Oracle on-prem to cloud (OCI/Azure), AIX to Linux migrations, database tuning, GoldenGate replication, or OEM configuration – I bring battle-tested skills and proven results.
🔧 What I Bring to the Table:
✅ Oracle Certified Professional (11g/12c/19c), Exadata X9M Engineer, MySQL 8.0 Pro
✅ Deep experience with Exadata, ZDLRA, ODA, Oracle Cloud (OCI), and OEM 13c+
✅ Architected zero-downtime migrations (non-GoldenGate, non-ZDM)
✅ Performance tuning using AWR, ADDM, SQL Profiles, and advanced indexing
✅ Experience with GoldenGate, bi-directional replication, and DR setup
✅ Cloud migrations: Exadata → OCI/Exa-CC, including ZDM-based moves
✅ Managed high-volume, high-availability systems across Finance, Healthcare, and IT
📌 Recent Success Stories:
🚀 Migrated mission-critical Oracle databases to Exa-CC using ZDM
🔄 Designed MAA architecture with full DR on Exadata & ZDLRA
🔧 Resolved complex performance issues using SQL rewrites and advanced diagnostics
🔒 Set up bi-directional ZDLRA replication to ensure zero data loss
Let’s talk if you're looking for a reliable, expert-level DBA who understands both the big picture and the fine-grained technical details. I work with precision, speed, and care — ensuring your database infrastructure runs like a well-oiled machine. 💡
