Randolph, VT · October 2025 to present
- Operate an independent product pricing and revenue operations practice. Designed, built, and shipped five live web applications solo using AI-accelerated development workflows with a layered review step.
- Built Pricing Workbench, a live pricing analysis application with three linked modules: a revenue and margin forecast for bundle and subscription price changes, a research module that designs and analyzes willingness-to-pay studies and returns a calibrated result to the forecast, and a volume, mix, and price variance model for forecast misses.
- Built the research module's statistics to hold up with small enterprise samples: exact confidence intervals at any sample size, a finite-population method for known account lists, and Van Westendorp results that reproduce the R package pricesensitivitymeter on a checked-in fixture.
- Designed, built, and launched Left Unspent, a live subscription personal finance product: two-tier pricing with monthly and annual plans, a 14-day application-side trial gate, and complete Stripe billing including Checkout, signature-verified idempotent webhooks, the Customer Portal, and Radar fraud monitoring.
- Built and shipped Revenue Healthcheck, a live React diagnostic application with four scoring modules covering pipeline health, forecasting accuracy, unit economics, and funnel efficiency.
- Own all production infrastructure for Left Unspent and Revenue Healthcheck (Vercel, Supabase with Postgres and row level security, passwordless authentication, email deliverability, Sentry monitoring), directing an AI-assisted development workflow with a layered review step.
