PERSONAL SYSTEMS / FIELD NOTESMessage the sysop
ENGINEERING / AGENTS / PRODUCT ARCHITECTURE

I build systems that have to work — and explain themselves.

I am an engineer who likes consequential systems, explicit boundaries, and tools that make difficult work feel calmer. Lately that means agentic software, model governance, and a new product boundary for retail operations. Earlier it meant Elixir platforms, Kubernetes before it was fashionable, Ruby systems, and a formative amount of time on BBSes.

Working principles PREFERENCES, NOT COMMANDMENTS

01

Reviewable automation over seamless execution

When an agent changes business state, a person should be able to inspect the proposal and say no — even if that adds a step.

02

Checkable evidence over polished explanations

Good explanations matter; verifiable sources matter more.

03

Technical influence over title progression

Step into management when the team needs it; return to hands-on work when that fits.

04

Learning in public over waiting for polish

Publish early experiments without selling them as finished products.

04 / Resume & contact FILE AREA

Start a conversation.

Engineering leadership, agent systems, and products where architecture and human judgment both matter.
