The work
What each project was, and what I was responsible for.
4.1
Loyalty Merchant Rewards
Merchant loyalty platform · 2026 · Lead Product & Development Consultant
- A loyalty program for small merchants, sold through independent agents and POS partners. The redemption portal existed; what didn't was a way for the channel to administer the program without going through LMR staff. I built that — enrollment, points, billing, and the partner API the growth strategy depends on.
- Fixed price, six milestones, each with written acceptance criteria.

Virtual patients
GigXR · 2021–present · SVP Product Development
- Simulated patients for clinical training: volumetric capture in place of standardized patient actors, multi-branch scenarios that respond to intervention, and most recently natural-language conversation.
- The hard part throughout is fidelity. A patient who presents subtly wrong teaches the wrong pattern.

4.3
GigXR Credits Service
GigXR · 2024 · SVP Product Development
- Usage metering and billing for AI features, built 0-to-1 and deployed to production on AWS.
- The interesting problem was never the infrastructure. It was finding a unit an institution could budget for in advance and audit afterwards.

4.4
Persim
Personal project · 2025
- A prompt authoring and evaluation platform. Personas are authored against a grounded knowledge base, then tested across thousands of parallel conversations and multiple models to surface drift no single transcript reveals.
- Built for my own work. GigXR used it on real patient scenarios. In private beta at persim.app.
