Background

About Me

I'm Daniel Haines — a systems integration and automation builder based in Lancaster, PA. I work across business applications, internal tools, infrastructure, data workflows, and AI-assisted operations to make complicated work more dependable.

I'm currently open to hands-on contract, contract-to-hire, and longer-term roles, as well as focused collaborations with other entrepreneurs. I care about systems that are reliable, understandable, and maintainable by the people who rely on them.
