Read the full case studyVouchernaut is a UK shopping guide with checked codes for 995 shops, a shop, comparison tools for phones, broadband, energy and airport parking, What's On listings, guides and a platform for brands. The founder and sole operator role covered every job: building and running the original site alone from 2016 to 2022, then rebuilding it at vouchernaut.com in 22 days in 2026.
- Rebuilt Vouchernaut from an empty repository to fifteen live products in 22 days: 772 commits and about 530,000 lines of code, 145,000 of them tests.
- Wrote the specs and made the product calls while AI agents did the typing across 203 Claude Code sessions, with every result checked against its spec before it went live.
- Shipped store pages for 995 UK shops, a shop of 5,220 products with price watch, a phone finder, a broadband checker, an energy comparison, 21,087 What's On listings, airport parking, discount hubs and group cashback.
- Built Vouchernaut for Brands, with a console, a partner API, a verification widget, reports and a Shopify app, from numbered PRDs in 26 hours.
- Designed the site, the brand console's design system and Vinny, the mascot, remade in clay.
- Built and operated the original programmatic-SEO voucher platform alone for six years at 90% margins, with pages for 100,000+ brands reaching 250K sessions a month and no paid spend or content team.
