About Me

Building reliable operations through software and system support

I am a software engineering professional experienced in supporting and improving Transport Enterprise Applications (TEA) and Warehouse Management Systems (WMS) in high-availability logistics environments.

My day-to-day work includes requirement gathering, Angular enhancements, backend root cause analysis with Java Spring Boot, and SQL-driven reconciliation and reporting improvements.

I focus on improving incident resolution time (MTTR), reducing reconciliation errors, ensuring high availability, improving delivery continuity, and translating business and operational needs into practical technical solutions.
