Everything below is built, and the linked products are live. I designed and built each one.
Studio SaaS · Live in production
PerformanceTracker
Performance tracking for slow-motion strength-training studios and franchises. Founded 2010; in 2026 I rebuilt it from scratch in two months and live-migrated its entire history out of FileMaker while studios kept training.
- Multi-tenant FastAPI + SQLAlchemy + PostgreSQL, React + Vite, Docker
- Tenant isolation enforced by tests — CI fails on any unscoped query
- 700,000+ sessions · 8,800+ clients · 420 machines migrated with row-level audits
- Multi-studio/franchise rollups, paper-to-digital conversion service

Consumer app · Live
REP 10·10
"A coach that talks you through every rep." A voice-only, hands-free strength coach that runs the whole session aloud — cadence, cues, weights, and rest — so your eyes stay shut and your hands stay on the machine.
- Built on the platform's 700,000 recorded training sessions
- Installable PWA; no account required to start
- Per-machine cue families; time-under-load verdicts drive the next weight

Selected project · Legal-tech
Codify the Code
A compiler for law. It parses statutory text into scoped definitions and conditional rules, then evaluates fact scenarios against the codified law with full derivation traces. It gives honest stops instead of guesses when the text hands judgment to a human, requires an explicit date for every lookup, keeps version history instead of deleting anything, and was validated by blind conformance testing against a synthetic statute with known answers. The same AI-accelerated build discipline, applied to an entirely new domain.

Marketing engine · Built
Ads
A social-advertising engine that turns anonymized member results into geo-tagged, studio-branded campaign creative — auto-generated captions, QR codes, and tile artwork ready for posting.
Internal to the platform
Creator referral engine · Built
PodTracker
A referral engine built as a search engine: it captures what a creator actually said (podcast and YouTube transcripts), makes the quotes searchable, and places the creator's products alongside every result — plus a crawlable Guides publishing layer on a dependency-free Python server.
