I'm a backend engineer at Wipro in Pune, building production REST APIs with Java 17 and Spring Boot 3 for VodafoneIdea's telecom order management system, as part of a 7-member team. I cut average response time by about 30% through MySQL index tuning and query restructuring, and traced a recurring order-dispatch timeout to an unindexed foreign key lookup.
Outside work I contribute to open-source Java projects, mostly libraries I use or admire. I start by reproducing the problem, check it isn't already reported or fixed, and then send a small, well-tested change.
