I build and own end-to-end data infrastructure at SPARX, a healthcare analytics company, from cloud platform and pipelines down to compliance and security governance. I care about systems that are correct, observable, and hard to break, and I tend to go deep on whatever layer the problem actually lives in, whether that is a token lifecycle bug, a warehouse migration, or a packet that will not traverse a NAT.

• Senior Software Engineer and Technical Lead at SPARX, owning data pipelines, cloud infrastructure, and HIPAA / SOC 2 posture
• Based in Bangalore, India, working remote
• Currently leading a Redshift to Snowflake migration and hardening platform security
• Long-term: open source maintainership, conference contributions, and building things that outlast the sprint they were born in

• A Go backend on Fiber v3 with Auth0 RBAC and Snowflake integration, designed around HIPAA-compliant architecture
• Snowflake security controls: dynamic data masking, row-level security, network policies, and tamper-detection alerting
• AstraLink, a WireGuard-based NAT traversal system targeting OpenWRT and ARM hardware, with a C/C++ hub agent and relay server
• A home network built on OPNsense (Protectli) with UniFi switching, because the lab is where the fun bugs live

Always happy to talk distributed systems, security, and the occasional packet that refuses to route.
