Situation
At my internship, every new API endpoint required a developer to manually write a Postman collection, which often took 2–3 hours per endpoint and frequently went out of date within a week because updates weren't reflected.
Task
I was responsible for documenting our team's internal APIs — a task that occupied most of one day per week and was universally disliked because the docs were stale almost immediately.
Action
I investigated alternatives and found that our FastAPI framework could auto-generate an OpenAPI spec from code annotations. I wrote a script that exported the spec to Postman format and committed it alongside code on every PR. I documented the three-line setup in a wiki page and demoed it to the team in a 10-minute Slack Huddle. I then retroactively added annotations to the 14 existing endpoints over two evenings.
Result
API documentation time dropped from ~10 hours/week across the team to near zero — it was now automatic. The collections were always up to date with the code. My manager cited this as a team-wide quality improvement in my internship feedback and nominated me for the "proactive contributor" award.
