OAuth2 PKCE lands in the auth service

Migrated three repos to OAuth2 PKCE, closing a critical security gap.

This week was dominated by a deep dive into authentication security. The main focus was implementing OAuth2 PKCE across three repositories, a task that required meticulous code reviews and refactoring of legacy auth flows. The shift wasn't just technical—it was a strategic move to align with modern security standards. Debugging token expiration issues and reconciling state management differences between repos kept the coding sessions intense. The payoff? A unified, future-proof auth system that's already easing deployment headaches.

Commits vs. Caffeine
Peak productivity hit on Tuesday with 10 commits, fueled by a 5-hour caffeine binge. Thursday and Friday slowed down to 2-1 commits each, likely due to context-switching between auth and frontend work.
