Day 28 of building a sports team communication app.
Took the last couple days off/slow as my parents came into town to visit us and the kids. Managed to get a couple hours or so to continue working and start on the core feature of the app -- chat.

Day 26/27 of building a sports team communication app
We’re winding down the last few days of 2025. I started posting more regularly on social media towards the end of the year, and I hope to maintain that momentum to get this app out to real users soon!

Day 24 of building a competitor to TeamSnap
We now add the ability to attach photos when creating bulletin posts. Claude Code and the Compose Multiplatform's open source library peekabo really streamlined how quickly this feature was implemented.

Claude Code is great but doesn't always come up with the most efficient solutions which can mean 💸💸. So today I was focused on improving efficiencies for database reads and writes when pinning and unpinning posts.

Hooked up the bulletin list view with the backend so we now load real data. Next up, we gotta create a button to allow actual creation of posts, but only allow admins to create posts and not players. Stay tuned!

No fancy UI work today, just adding data layer to start connecting the bulletin screens to actions. Lots of refactoring from a lot of the work that Claude did to fine tune and clean things up since I actually DO read the code 😛

How do you motivate your partner to exercise regularly without making it feel like an attack? Not because you want them to look any differently, but because you genuinely believe it’s better health wise both mentally and physically. Doesn’t even have to be a lot of exercise.
