About Me

Engineering interoperability at the edge of care.

I'm an Integration Engineer with 1+ years of experience designing and building the data infrastructure that powers modern healthcare — from community clinics to large health systems.

My work sits at the intersection of clinical workflows, regulatory compliance, and distributed systems. I believe that the right integration architecture doesn't just move data — it enables better patient outcomes.

Based in Akola (Maharashtra, India), working with health-tech organisations globally. Passionate about open standards, FHIR adoption, and removing the friction from care delivery.
