Rajamohan Masa

I've supported database environments for Ciklum India, Infogen Labs, IMPELSYS, and VSM Infotech, administering PostgreSQL and developing Microsoft SQL Server solutions for business-critical applications.

For Mirion Technologies, I planned and executed PostgreSQL major-version upgrades, managed Amazon RDS PostgreSQL backups and PITR testing, and automated health checks and backup validation with Bash scripts. I also developed SQL Server views, tables, stored procedures, triggers, and user-defined functions.

I've upgraded PostgreSQL from version 12 to 15 with zero data loss, maintained rollback procedures, configured WAL archiving, and tuned databases through indexing, autovacuum, checkpoint tuning, partitioning, and EXPLAIN ANALYZE.

I bring 7+ years of database administration, development, and 24×7 production support experience, collaborating with application, infrastructure, and DevOps teams to resolve incidents and meet SLA commitments.
