About
Engineer first, for 18 years
I studied Electrical Engineering at IIT Roorkee, then spent ten years at HCL Technologies building telecom, security and VoIP software for Openwave, Symantec, Cisco and Telstra/Digi.
Since 2018 I have worked independently, delivering web, mobile and AR work for clients across Europe and India. Most of my work now is AI: retrieval pipelines that cite their sources, agents that ask before they act, and the billing, auth and observability that turn them into real products.
I work directly with founders and teams, write the code myself, and stay until it is running in production.
