Day with AI: Custom Task Management in 2 Hours, Fitness App Tweaks, and 8 Commits on a Saturday.

Built custom task management with time tracking to replace an external service. Plus training plan tweaks, meal adjustments, and a full PRD for a fitness app. 8 commits, 8 sessions.

Day with AI: Custom Task Management in 2 Hours, Fitness App Tweaks, and 8 Commits on a Saturday.

What I worked on

Saturday. The day you decide paying for task management is pointless — and build your own in an afternoon.

What I did

Task management — from zero in 2 hours

Main project of the day. I had an external service for time tracking and tasks, but it never fit my workflow. So I ditched it and built my own system. Shell scripts for creating tasks, automatic time tracking via session record integration (no manual timers), automation hookup for creating tasks from meetings, and a session start dialog — every work session begins by picking a task.

Result: 7 commits just for this part. From "I have no task manager" to a fully functional system with automatic time tracking. Zero external dependencies.

Tracked time from log: 8h+ of work → 2h. Custom tool, built to measure.

CRM workflow fixes

Morning session fixing CRM automations. Upsert strategy (create or update), workflow cleanup, and prep for sharing. An eight-hour job done in thirty minutes.

Fitness app — training plan and meal adjustments

Tweaks to a personal fitness app. Adjusting training plans based on real experience — some workouts feel better than others, so I adapted the structure. Added finer weight increments (1 kg steps). On the food side: expanded recipe selection, rounding to full packages (yogurt in 200g containers, ham in 100g packs — not random grams). Plus a complete PRD for future development.

Tool research

Evaluated a knowledge graph tool for better repo navigation. Interesting concept — AI builds a relationship graph from code, docs, and media. Backlogged for now.

What I learned

  • Custom tools > paid services when you know exactly what you need — less overhead, perfect workflow integration
  • Automatic time tracking via session records eliminates forgetting to start timers — just work and time counts itself
  • Fitness plans need real-world testing — theory looks great on paper but actual training reveals what works
  • 8 commits on a Saturday sounds like workaholism, but half of them are "finally have a system that fits"
