Talking about feature flag debt at DevOpsDays Prague

On Monday 5 October I am speaking at DevOpsDays Prague. The talk is called When Your Safety Net Becomes a Trap: Cleaning Up Feature Flag Debt.

Feature flags are one of the most useful tools in a modern DevOps toolkit — progressive rollouts, A/B tests, safer deployments. They also accumulate quietly, until a codebase is a maze of stale conditionals nobody dares delete.

The talk is about treating that as a first-class cleanup project rather than a chore nobody owns: auditing a large flag inventory, classifying every flag as active, stale, dead or zombie, and removing the dead weight while the system stays live and under load.

How I worked out which flags were still referenced, and how the removal was staged without regressions, is the part worth seeing in person. I will keep that for the room.

Details are on the talk page, and the slides will go up there after the event.
