Projects

The things I'm building right now. Most run on Cloudflare's edge stack (Workers, Queues, D1, KV) with Anthropic and OpenAI APIs doing the heavier reasoning.

Split Test Pro is a Bayesian A/B testing platform for Shopify, in production with paying customers. It has a custom Beta-Binomial / Normal stats engine, LLM-powered pre-launch reviews, anomaly detection, and post-experiment analysis. Most of the engineering writeups on this site are about it.

CRO Audits is a productized conversion-optimization audit delivered on roughly quarterly cycles. The recent rebuild runs a multi-stage Claude pipeline: crawl a site, classify pages with Haiku 4.5, screenshot the highest-conversion-value pages, and run a vision audit with Sonnet 4.

Coupon Defender detects coupon-code abuse and redemption anomalies for Shopify stores, currently in beta with merchant pilots.
