Doby Baxter

Doby Baxter Computing • Independent Software Engineering

Software should never fail a person in silence.

I build reliable Python systems, developer tooling, and scientific software: systems that catch a wrong state early and explain it in words a person can act on. My focus is configuration validation, deterministic AI workflows, and clear error messaging.

Through Doby Baxter Computing I offer fixed-price reliability reviews for small businesses. Fully remote and read-only: nothing in your system is touched. → See services
