I build the softwarenobody demos on stage.

Solar CRMs. Commission math that used to live in a spreadsheet named FINAL_v4_USE_THIS. A scheduler for cookie booths. Flashcards for electricians. Unfashionable problems, shipped and in use.

Selected work

Scout CRM

Four years of a solar sales team's whole working day in one platform: leads, proposals, installs, payroll. The kind of system where a bug means somebody doesn't get paid on Friday, so it didn't have bugs on Fridays.

Commission Calculator

A public SaaS that turns solar commission math — tiers, splits, clawbacks, adders — into a number a rep can trust. Built because every office in the industry was running the same haunted spreadsheet.

Cookie Booth Scheduler

Troop booth sign-ups without the group chat. Slots, parents, coverage, conflicts — the scheduling problem enterprise software charges five figures for, aimed at volunteers who have twenty minutes.

“Nobody has ever asked me what framework it was written in. They ask whether the number is right.”
— the whole design philosophy, more or less

Got an unglamorous problem?

Freelance work, contract builds, or a full-time role where the software has to actually hold up on a Friday. Tell me what's broken.
