01 — Overview
Separate platforms, one clinical day.
Clinicians worked across more than one healthcare platform. This project connected them: one sign-in through Auth0, patient data and appointments moving between systems over REST APIs, and clinical workflows that continue from one product into the next.
02 — Problem and context
Every hand-off cost a login and a re-type.
Separate platforms meant separate sign-ins, patient details entered twice, and appointments that lived in one system but were needed in another.
[Add specifics: which platforms, who used them, what the gaps cost day to day.]
03 — Goals and constraints
What had to be true.
Goals
- One sign-in across platforms
- Exchange patient data without double entry
- Keep appointments in step on both sides
- Let clinical workflows cross product lines
Constraints
- Sensitive health data in every request
- Existing systems and APIs stay in place
- [Regulatory requirements]
- [Timeline or team constraint]

05 — Architecture and technology decisions
How the platforms talk.
Identity goes through Auth0; data goes through an integration layer. Step through it, or let it play once.
Platform A

OAuth 2.0 · OpenID Connect
Platform B
Partner platform

Patients · appointments
SSO and data flow · step 4 of 4
06 — Key engineering challenges
Where it got hard.
One identity, many systems
Matching users and sessions across platforms that were never built to share them.
[How accounts were linked]
Data that must agree
Patient and appointment records can change on either side; each field needs one owner.
[Ownership rules used]
Workflows across boundaries
Moving a clinician from one product to the next without losing the patient in context.
[How context was passed]
07 — Screenshots and walkthrough
The flow, screen by screen.
08 — Solutions and tradeoffs
Decisions, with their price.
| Decision | Why | Tradeoff |
|---|---|---|
| Auth0 with OpenID Connect for SSO | A standard protocol both platforms can trust, without sharing passwords. | [Add] |
| A REST integration layer for patients and appointments | Each platform keeps its own data model; the integration translates between them. | [e.g. retries and reconciliation to handle] |
09 — Outcomes and lessons

[Verified outcome]
- Agree on who owns each piece of data before writing sync code.
- Treat sign-in as part of the product experience, not only plumbing.
- Make integration failures visible: logs, alerts and a clear way to retry.
