Hi, I’m John.

I’m a senior software engineer and associate manager at impact.com. I’ve spent eight years building data pipelines and running the services behind them. These days, I also build context systems and developer tools for AI agents.

Outside work, I build open-source tools, games, and websites through Augustino, my independent software business. Away from the computer, I’m usually in the garden, playing guitar, or hanging out with my dog, Nova.
