Our initial benchmark numbers looked promising in staging but fell apart under production traffic patterns. The difference? Staging used uniform request distributions while real users exhibit bursty, correlated behavior that exposes different bottlenecks entirely.
The team’s relationship with technical debt changed when we started categorizing it. ‘Reckless’ debt (shortcuts we knew were wrong) gets prioritized for immediate paydown. ‘Prudent’ debt (intentional tradeoffs) gets documented and scheduled. The distinction removed the guilt and the arguments.
We adopted a writing culture where every significant technical decision gets documented in a lightweight RFC. These aren’t formal or bureaucratic — just a shared Google Doc with problem statement, proposed approach, alternatives considered, and decision rationale. Six months in, the archive has become our most valuable knowledge base.
Feature flags transformed our release process more than any CI/CD improvement. Decoupling deployment from release meant we could merge code daily, test in production with internal users, and gradually roll out to customers — all while maintaining the ability to instantly revert without a code deployment.
We’re still iterating on all of this. In six months, some of these practices will have evolved or been replaced entirely. That’s the point — the system should never feel finished.
