I build resilient database platforms and migrations across PostgreSQL, ClickHouse, AWS, and Azure Databricks.

At Storyclash, I lead a dual-engine PostgreSQL and ClickHouse environment supporting production-grade SLAs. I built PostgreSQL HA clusters with automated failover, achieving 99.9%+ uptime.

I moved reporting workloads to ClickHouse, cutting P95 query latency by 80% and reducing OLAP pressure on transactional systems. I also migrated 15+ Oracle databases to PostgreSQL with Python validation automation and zero data loss.

Previously at MACOM Technology Solutions, I led Oracle-to-PostgreSQL migration work that eliminated proprietary licensing costs by 60%. I also delivered SAP disaster recovery, PostgreSQL replication architecture, and automated monitoring and deployment workflows.

Across FirstCry, Cross Country Healthcare, CyberTech, Wipro, and Mphasis, I've optimized and operated Oracle, SQL Server, PostgreSQL, and MySQL platforms. I build cloud migrations, lakehouse pipelines, and reliable data systems for large-scale operational and analytical workloads.
