Java Technical Lead at BNSF Railway modernizing railway systems with 30+ microservices and event-driven integrations.

United States

Message

At BNSF Railway Company, via Infosys, I lead technical delivery for a railway modernization program. I guide a 30+ member engineering team and have mentored 30+ engineers.

I’ve designed and delivered 30+ Java and Spring Boot microservices and event-driven integrations using RabbitMQ and Kafka, handling approximately 1,000 messages per second. I maintain 90% unit-test coverage and zero critical SonarQube issues while releasing every sprint.

Earlier, at BNSF Railway Company via TCS, I built and maintained railway-operations applications, including REST APIs and reusable components integrated with enterprise systems.

At Tata Consultancy Services, I built a billing tool that automated Excel-based processes and improved user efficiency by 75%. Earlier, at Anadocs IT Solution, I reduced transaction-processing latency by 70% and improved loan-disbursement efficiency by 80%.
