About me

Legacy mainframes run the world's most critical systems and most organizations still use it, not by choice, but because migration is genuinely hard. For 20+ years I've been the architect who makes it possible: $20M+ in projects delivered, 500K+ Medicare members migrated without a single SLA breach, and $250K in mainframe costs eliminated on a single recent assignment.

I work across the full modernization stack — reverse-engineering decades-old COBOL, deploying cloud-native microservices on AWS, designing DB2 data architectures, and leading onshore/offshore teams across Healthcare, Banking, and Capital Markets in the US and UK. AWS Certified Solutions Architect. PMP certified.

Right now I'm doubling down on AI, pursuing an MS in Data Science (AI & ML) at IIITH while building hands-on Generative AI, Machine Learning projects — because the next wave of modernization won't just lift and shift; it'll make legacy systems intelligent.

Kiran and I were part of the same group supporting projects of wealth management portfolio for Bank of America. Kiran always had the big picture in mind and provided wholistic solutions that involved cross technical platforms. His approach towards the long term sustainability and scalability of a IT solution is worth mentioning. Many projects that he had to support were highly time sensitive and demanding yet his efforts made them very successful. His ability to quickly adopt to new systems and learning new skills time and again has been his great strength.

I worked with Kiran for GE in UK as TCS consultants and he was really a thorough professional to work with. He is a quick learner and a team player. His technical acumen, clear communication and responsible attitude were the assets for the team. In a matter of days he understood the application landscape and contributed immensely to the quality of deliverables. I am sure wherever he goes, would shine and would make a difference!.
