Hi, my name is

Rajkeshwar Prasad.

I build things for the financial web.

I'm a Lead Fullstack Engineer based in Nürnberg, Germany, specialising in enterprise Java/Spring Boot backends and modern frontend architectures. Currently at ING GmbH (via HCLTech), building systems that serve hundreds of thousands of users daily.

Over 15+ years I've shipped production systems for Bank of America, DBS Bank, and ING — from microservices chatbots to enterprise component libraries. EU Blue Card holder — no sponsorship required.
