My GSoC project with D4CG Organization: a complete SMART on FHIR experience, from launch to data display, polished for real-world use.
I contributed to Data For Common Good as a Google Summer of Code contributor, building a polished end-to-end SMART on FHIR app. This page is a single place to explore the journey, the migration from Code-A to Code-B, and the final deliverables.
Deliver a production-ready SMART on FHIR app with modern UX and secure backend.
Optimized Next.js frontend, authenticated FHIR access, clean APIs, and full docs.
All deliverables completed and merged. No work left pending.
Build a complete SMART on FHIR application with a refined user experience and extensible backend services.
Implemented responsive UI, SMART launch, FHIR data flows, backend endpoints, caching, pagination, and deployment-friendly configs.
End-to-end flow operational with sample data, telemetry, and clear documentation for onboarding.
Frontend, backend, infra scripts, and a migration from Code-A (React) to Code-B (Next.js), all finalized.
Use-case discovery, scope refinement, milestone planning.
UI scaffolding, auth, FHIR integration, core components.
QA, performance, accessibility, and DX improvements.
Setup guide, contributor docs, deployment notes, and demo walkthrough.
| Feature | Code-A (Old) | Code-B (New) |
|---|---|---|
| Speed | Slow (downloads every time) | Fast (caches data) |
| Data Size | Huge (all rows) | Small (paginated) |
| Usability | Raw CSV (hard to use) | JSON + search (easy) |
| Server Load | High (no cache) | Low (cache + pagination) |
| Bandwidth Usage | High (full dataset each time) | Low (only requested data) |
| Rendering | CSR only | SSR/ISR + RSC |
| Routing | Client router | App Router with nested layouts |
| DX | Ad-hoc structure | Typed modules, linted CI, clear folders |
The migration, UI polish, backend integration, and documentation are complete. No pending work remains.
This report captures goals, achievements, and links to all code for my GSoC with D4CG, including the full Code-A → Code-B migration.
Elegant components, fluid type scales, and full dark/light support.
Secure authentication and session handling aligned with SMART on FHIR.
Typed endpoints to fetch and present resource data with robust error handling.
Clear project structure, env config, and scripts for quick onboarding.
