At OnMobile Global Ltd., I supported 24×7 telecom production operations for platforms serving 70M+ active users. I monitored service health against operational SLAs and handled P1/P2 incidents using Linux diagnostics and Java/Log4j log analysis.
I investigated PostgreSQL performance issues, including slow queries, blocking sessions, lock contention, and deadlocks. I also monitored scheduled batch jobs, investigating failures and delays and re-running or escalating jobs in line with SOPs.
I developed Bash scripts for service health checks, log rotation, and diagnostics, and documented 20+ SOPs and runbooks. I also supported release and patching checks, change activities, and incident coordination through resolution and RCA.
At Logile Inc., I provided L2 support for an enterprise retail SaaS platform, investigating tickets and CloudWatch alerts with Linux and SQL diagnostics. I performed release health checks and log validation, executed 300+ staging test cases, and coordinated with teams to track incidents through resolution. During my career break, I studied AutoSys fundamentals and practiced REST API testing with Postman.
