Alex Britton
Forward Deployed Engineer at Driveline Baseball
/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. For the fuller personal context, read a little bit more about who I am.
