products & backend
systems.

Trainee Engineer → Software Engineer → Senior Software Engineer

• ▸Architected a configurable, provider-agnostic payment gateway abstraction using .NET Core DI, so adding a new provider requires only implementing a standard interface and a config entry, with no changes to existing business logic
• ▸Led backend integration of ABDM (Ayushman Bharat Digital Mission) into an oncology EMR, implementing ABHA linking, FHIR-compliant health record exchange, and consent management, enabling patients to view and share their records directly across hospitals
• ▸Designed a background-service and outbox-pattern architecture with per-workflow job processors to handle ABDM's async accept-then-callback protocol across data-sharing and record-linking workflows
• ▸Built chemo and radiation treatment planning modules aligned with National Cancer Grid protocols, including a calendar-based treatment timeline view, replacing manual day-by-day scheduling with protocol-based plan generation
• ▸Led development of a multi-role React Native application (Patient/Doctor/Admin/Contractor) with OTP login, secure in-session profile switching, biometric verification, and SMS-based OTP auto-read; published to Play Store with integrated appointment payments
• ▸Refactored repetitive modal and dropdown UI across the application into a single reusable context-based modal hook, removing duplicated JSX and simplifying state handling
• ▸Migrated frontend build tooling from Create React App to Vite, improving build and dev-server performance
• ▸Refactored JWT handling from manual body-based transmission to HttpOnly cookie-based storage, improving auth security
• ▸Integrated the Agora video consultation SDK with an async/await architecture, and built an Azure Blob Storage pipeline for call recordings with a background service handling configurable retention and deletion
