Prompt
Walk me through your project end-to-end:

-
Key constraints (scale, latency/SLA, security/compliance, deadlines, legacy systems).
-
Your role and ownership
-
What were your specific responsibilities? Were you the sole owner or supporting another engineer?
-
Key technical and product decisions
-
Architecture/stack, data model, APIs, deployment, testing, observability.
-
Product scoping and prioritization.

Trade-offs made
-
Alternatives considered and why you chose one path over another.
-
Results and impact
