Message

At Tech Mahindra, I work on critical corporate banking applications for Santander. I streamlined incident management, root-cause analysis, bug fixes, and enhancements, reducing production incident turnaround times by 30%.

Previously at Tech Mahindra, I migrated corporate banking microservices and containerized them with Docker, while automating deployments through GitHub Actions. I also upgraded Java 8 to Java 17 and migrated IBM API Connect from V5 to V10.

At IBS Software, I re-architected an airline operations system from a monolith to modular microservices. Through Code As A Story, I create a series that explains computer science and backend engineering in a simple, story-driven way.
