Longitudinal Patient Timeline UI & Aggregator

[inteee]

Context: LumenHealth EHR

When a doctor opens a patient's file, they need to see their entire medical history (all past encounters, vitals, and notes) on one scrollable, chronological screen.

Concurrent Boundary (How to work unblocked)

Create a complex mock JSON object representing 3 past encounters with fake nested vitals and notes. Do not wait for the real data to be generated.

Backend Scope (apps/api/src/modules/patients/history.controller.ts)

1. Build a heavy aggregation endpoint GET /api/v1/patients/:id/history.
2. It must fetch the Patient, all past Encounters, and $lookup (join) the Vitals, Notes, and Diagnoses for each encounter, sorted newest to oldest.

Frontend Scope (apps/web/src/app/dashboard/patients/[id])

1. Build the Medical History view featuring a vertical timeline connecting the visits.
2. Implement lazy-loading/pagination. Only load the last 5 encounters, fetch more when the user scrolls to the bottom.
3. Design expandable accordion cards for past visits. Clicking a visit expands it to show the vitals and notes from that day.

Acceptance Criteria

• The backend aggregation endpoint completes in under 300ms (ensure proper MongoDB indexing on patientId).
• The frontend successfully renders nested data and handles pagination smoothly.

Hello maintainers .

I am a committed open-source developer with experience delivering production-ready solutions across Web3 and full-stack systems. I’ve worked extensively with Stellar infrastructure, Soroban smart contracts, backend services, and React-based frontend applications, with a strong emphasis on performance, structure, and intuitive user interfaces.

I’m comfortable taking ownership of tasks from initial analysis through to implementation and review. This includes evaluating the problem space, designing a clear technical approach, writing clean and maintainable code, adding appropriate tests, and ensuring documentation meets the repository’s standards.

The scope of this issue aligns well with my experience, and I’m confident I can deliver a thoughtful and reliable solution within a reasonable timeframe. My GitHub profile reflects my ongoing open-source contributions and technical background if you’d like to review my previous work.
I value clarity in communication, maintainable architecture, and collaborative development, and I’d be excited to contribute meaningfully to this project.

Thank you for your consideration.
