Software & business systems

Projects I’ve built.

Each case tells the problem, what I built and what changed, then how it fit together and the decisions behind it. Current work first, then five delivered systems.

Hiring for an AI or product engineering role?

Start with the Keystone platform: architecture, the recorded replay, decisions and controls. Then read the notice pipeline for applied AI under a real deadline.

Running a business with a workflow problem?

Start with the three websites and the clinic: delivery, handoff and what changed for the people using it. Then book a call.

Keystone platform

One platform for a real-estate investing operation · St. Louis

A multi-tenant backend and operator console that takes an investor from messy lead data to a closed deal: lead generation from public notices, market imports and inbound sites; follow-up in one CRM; an evidence-backed offer range; a photo-based property brief after the walk; and buyers matched to what comes through. Built for a first client, now being generalized for more than one operator.

Status
In development · one operator · first tenant was a client engagement
