I build backends AI agents can safely operate.

corral

Prove your tests would catch it.

Corral breaks your code on purpose and checks whether your tests notice. It plants faults that violate a stated guarantee, runs your own suite against each one in a sandbox, and reports how many it killed — measured by execution, never taken on a model’s word.

The constraint underneath is nemo iudex in causa sua: the party that did the work never certifies the work, and a run where the critic model matches the writer model is refused. It ships as one command, corral certify --local, against your own provider key with no server.

Unedited output of autonomous corral runs is preserved as evidence, defects included: corral-run-js-lru-cache and corral-run-python-ratelimit.

ProductBinder / WebOffice — private · commercial · in development

A multi-tenant publishing platform.

Product and listing management, a CMS with inline page and navigation editing, an events subsystem with full RFC 5545 recurrence, and a commerce layer covering rate cards, campaigns, invoicing, and accounting sync.

A Django/DRF core behind a versioned TypeScript SDK, consumed by a SvelteKit admin and server-rendered public sites. Fifteen-plus coordinated repositories with a cascading CI/CD pipeline onto self-hosted infrastructure. The largest system in the portfolio and the clearest evidence of working at platform scale — which is why it headlines despite not being clickable.

A commercial platform I’m building. It runs in production for a regional media business and is not yet on the market.

kirby-cost

The HERO System 6E build and cost engine, ported from scratch.

A from-scratch port of the HERO System 6E character build and cost engine, validated to 100% parity with the reference implementation across 656 fixtures, every character exact on every object. Parity is a release gate, not a one-time claim.

Ships no licensed Hero Games content. Part of the Kirby engine line, three separate zero-runtime-dependency Python libraries: kirby-cost costs a build, kirby-combat resolves 6E combat, and kirby-sheet reads a HERO Designer character and writes it back out as JSON, text, HTML, PDF, or .hdc. The credential here is the parity number, and it is checkable because the code is public.
