Alex Britton
Forward Deployed Engineer at Driveline Baseball · Co-founder of altr
/now
I am a forward deployed engineer at Driveline Baseball, building practical software, data pipelines, and internal systems close to the people who use them.
Right now I am focused on LLM-assisted workflows, agentic coding, and side projects that turn effort into compounding tools and assets. Outside of Driveline, I co-founded altr, an AI consulting firm in Tampa, where I build the MCP servers and agents behind our client work, a lot of it for commercial real estate. For the fuller personal context, read a little bit more about who I am.
