I design, build and operate an AI production pipeline that turns a written business brief into a deployed, working web application. Sole engineer across architecture, build system, deployment and operations. Selected engineering work: Built a provider abstraction layer presenting one client interface over multiple AI vendors. This let the entire system be migrated between providers without changing any of its sixteen call sites or its tuned prompts. Implemented technical SEO as a hard delivery gate rather than a checklist. An automated pass verifies every build against unique titles and meta descriptions, Open Graph tags, structured data, image alt text, favicon and sitemap, and a build that fails does not ship. Built an independent automated review stage that inspects each finished build and repairs what it finds before delivery. Integrated payment processing and transactional email, and built an admin console for operations. Reduced per build inference cost to under three dollars through prompt caching and effort tuning. Published the product as a Progressive Web App with a signed Android package.

Designed, built, deployed and operated several production applications end to end. A flight compensation claims tool, live and taking payments. It assesses passenger eligibility under EU261 and UK261 rules and generates claim letters carrying the legal citations airlines respond to. Rules engine, payment integration, scheduled follow up email, and a public claim directory. A quantitative research platform with a simulated perpetual futures exchange including fees, slippage, funding settlement, leverage and liquidation. Built an event driven backtester with no lookahead bias and out of sample validation, and a ledger reconciliation check that runs continuously and caught two real accounting defects. The study produced a negative result and I published it as one rather than presenting a curve fitted winner. A multi tenant SaaS with PostgreSQL tenancy and credit based billing. An AI assisted industrial and machinery design application. An Android application that backs up SMS and call logs to a desktop agent in real time over a hosted relay.
