Systems I shipped.

Built to answer a question I actually had. Public documentation where code stays private, open source where the code is ready.

Rebate Program Designer and Evidence Workflow

WattShed is live national rebate-program software with a public, no-login designer for all 50 states and DC. Its deterministic engine combines degree-day and modified-bin estimates with location-appropriate deemed methodologies where available. A Milam County case study demonstrates evidence review, qualification, quote approval, completion clearance, and payment-instruction records. Settlement remains simulated. WattShed has no payment processor, does not custody funds, and moves no money.
