I build secure, scalable full-stack platforms and API automation tools.

India
Message

I've built secure healthcare analytics platforms at Eli Lilly, API governance automation for PayPal, and communication workflows at Doosra. My work spans Angular dashboards, Node.js services, REST APIs, microservices, cloud deployment, and secure data access.

At PayPal, I lead development of PPAAS Validator, a CI-integrated platform that validates OpenAPI 3.0 specifications and blocks deployments with schema or design violations. I use Node.js, TypeScript, Spectral, GitHub, and Harness to improve API documentation consistency and platform-wide review efficiency.

I've also delivered healthcare data pipelines and search APIs, Twilio and CRM integrations, and stock and crypto trading integrations. I enjoy owning end-to-end delivery while collaborating across product, data, QA, DevOps, frontend, and backend teams.
