What I'm looking for

I'm looking to lead architecture and product engineering work where I can build scalable, maintainable platforms, mentor engineers, and drive reusable engineering standards across payments, embedded systems, automotive, or mining.

At HCL Technologies, I lead development for Caterpillar's Onboard Mining Star platform, supporting multiple ECM integrations. I've built a Generic Library Framework adopted across engineering teams and drive architecture reviews, standardization, code quality, and reusable component adoption.

Over 13+ years, I've delivered card management, payment, POS, banking, retail supply-chain, and embedded solutions at FIS, Cognizant, and Tata Consultancy Services. I lead and mentor teams of up to 13 engineers using C, C++, Python, Oracle, Linux, ISO8583, HSM, and OAuth2.
