Senior Software Engineer at Compare Credit

April 1, 2024 - Present

transitioned to direct employment after 3 years as an embedded contractor, taking on broader ownership across the engineering team. Core platform is a Next.js and TypeScript monorepo with Sanity CMS, deployed on Vercel, with Google BigQuery as central data warehouse. Led the migration to a new multi-product platform MVP — a Next.js/TypeScript solution with a dedicated Sanity workspace, full observability setup, geolocation, and CCPA compliance. Implemented a Sanity Presentation Tool for live draft preview directly within the CMS, enabling live preview and eliminating publish-before-review. Implemented a client-side routing layer using a Multi-Armed Bandit approach to optimize conversions by reading real-time Redis data and redirecting users to the highest-performing page variant. Built an AI-powered Compliance Bot that scrapes pages with Playwright and uses an LLM to flag regulatory risks, reducing manual review. Contributed to Trove, a Chrome extension built with React and TypeScri

The platform automatically scraped official government gazettes, parsed PDFs to extract potentially relevant legal updates, and routed flagged content for human review by legal specialists before being added to the regulatory database.
