I own the merchant admin portal and dashboard end to end, and I build the systems merchants use to test and sell their offers.

• Designed and shipped conversion-based reweighting and weighted variant routing for our Bayesian experimentation engine. Simulations confirmed it converges on the best-converting variant.
• Delivered the experiments system's first production release, with server-side caching, test coverage and an end-to-end test that runs from ad account to checkout to event validation.
• Built the commerce layer: orders dashboard, order-sync safeguards, order APIs, and refund and partial-refund flows for bundled offers. Also connected merchants' Shopify stores and ad accounts.
• Built the telemetry pipeline on RudderStack, Google Tag Manager, GA4 and BigQuery. It tracks model usage, cost and failures alongside section views, scroll depth and dwell time.
