What I'm looking for

I'm looking to build secure, highly available cloud database platforms, with ownership of AWS RDS, performance, HA/DR, automation, security controls, and compliance for mission-critical workloads.

At HDFC Securities, I administer a multi-engine AWS RDS fleet across Aurora PostgreSQL, RDS PostgreSQL, and Aurora MySQL for critical financial-services workloads. I lead database security, access governance, monitoring, performance tuning, capacity planning, and high-availability decisions.

I've also supported digital banking and enterprise environments at Uno Digital Bank, Cognizant, and Accenture, delivering backup and recovery strategies, AWS infrastructure, SQL Server performance tuning, migrations, and HA/DR implementations. With 10+ years in database operations and AWS Certified Solutions Architect credentials, I use automation and AI/LLM tools to speed query optimization, root-cause analysis, and production incident triage.
