We built a lightweight internal developer portal that aggregates service ownership, runbook links, API docs, and deployment status. It took one engineer three sprints to build using a static site generator, and it immediately became the first place anyone goes when an incident starts.
The team experimented with mob programming for complex features. Instead of one developer struggling alone with unfamiliar code, three or four engineers would work together for focused two-hour sessions. Velocity metrics initially looked worse, but defect rates dropped dramatically and knowledge silos disappeared.
What Changed
Accessibility improvements delivered unexpected business value. After making our checkout flow screen-reader compatible, we saw a 12% increase in completion rates across all users — the clearer interaction patterns helped everyone, not just assistive technology users.
Our API versioning strategy evolved through three iterations. URL-based versioning was too coarse, header-based was too invisible, and we finally settled on field-level deprecation notices with sunset dates. Consumers get twelve weeks notice before any breaking change takes effect.
