At CYBERTEC, I resolved more than 100 L2/L3 PostgreSQL production incidents for financial and enterprise clients, reducing mean resolution time by 30% through structured root-cause analysis. I also deployed Patroni and etcd high-availability clusters and performed controlled failovers.
At Chinmay Finlease Limited, I planned and executed a PostgreSQL v14-to-v17 upgrade with no unplanned downtime, and tuned OLTP workloads to reduce query P95 latency by 35%. I also implemented backup and recovery procedures with PITR and streaming replication.
At Shreeyansh DB Software Pvt Ltd, I deployed a SymmetricDS CDC pipeline between PostgreSQL and MS SQL Server, reducing reporting data latency from four hours to two minutes. I automated routine DBA tasks and authored PostgreSQL tutorials using Sphinx.
