I've been a software developer for over 12 years. My latest obsession is agentic coding tools like Claude Code. I'm hoping to find a role on a team that's big on AI tools for software development.

Simple Activity Tracker

Log events throughout your day
Express React

There doesn't seem to be a single activity tracker in existence that just ...tracks activities, until now! Oh, and I have to actually be able to export my data. And I'd rather not have to watch ads. And I'd like to be able to use it on my phone or computer. Is that too much to ask!?! This was just simple page I made to learn React years ago but I used Claude Code to give it a back end and host it at www.simpleactivitytracker.app in a single coding session!
