Lessons From Building Sehatdastak: A Hospital Platform With 100+ APIs

Context

Sehatdastak was part of the LCE LUMS accelerator — a full-stack platform for hospitals, clinics, doctors, and patients.

We had to support:

• Multiple roles (admin, doctor, patient, staff)
• Sensitive data (vitals, records)
• Complex flows (appointments, analysis, messaging)

Architecture Highlights

• React + MUI frontend
• Node.js + Express backend
• MongoDB with careful indexing
• Clear domain separation: Auth, Users, Records, Analytics, Messaging

What Went Well

• Investing early in role-based access paid off later
• Having a proper API contract between frontend and backend saved time
• Analytics on vitals became a strong differentiator

What I’d Do Differently

• Even more logging around critical flows
• Earlier investment in automated tests for core endpoints
• Design for multi-tenant from day one
