Spent three weeks on infrastructure for a to-do app nobody but me will ever use
Docker, CI pipeline, a staging environment, the works, for an app with maybe two hundred lines of actual logic. Realized halfway through I was avoiding the parts of the project that were actually hard, the UI decisions and the data model, by hiding in the parts I already knew how to do well. Finished the infra, still haven't touched the frontend. Portfolio projects apparently have the same procrastination traps as everything else.
