Lazy Brilliance

on YouTube ↗28m

" summary

Claims concrete: keeping old codepaths and feature flags lets a product manager flip core flows off or back on immediately, avoiding developer hotfixes and regulatory downtime. Built a typed feature capabilities layer with available ready completed flags, per-feature React hooks, a feature-flag service with Gateway IP enrichment and user tags, and 1%→100% rollout gates. Two incidents: card-stock outage and Nigerian currency rule change; recovery requires no devs needed for toggles and a fast build of a USD flow that worked in production.
