Shift is a native iOS app I built for people whose work schedule changes week to week. It tracks shifts on a monthly calendar, works out gross income from hourly or fixed rates, and handles recurring shifts and reusable presets. It also doubles as a study planner, with subjects, exams and assignments alongside work. Its built-in assistant runs on Claude: you describe your schedule in plain language and it proposes the entries, which you confirm before anything is saved, with your API key kept in the device Keychain. Built with SwiftUI and SwiftData, it includes a home-screen to-do widget, JSON export and full English and Spanish localization, and it keeps all data on the device.

Autoclub Trackdays is a live production site I built for a Madrid car dealership with over 25 years in the trade. It's an Astro and Tailwind CSS build deployed on Cloudflare that ships with zero client-side JavaScript: a searchable catalogue with a dedicated page per vehicle, plus sections for buying, selling and custom orders. Performance and SEO drove most of the decisions: structured data for search engines, link previews for WhatsApp and Instagram, and responsive WebP photography served from its own image domain. It also ships with a custom admin panel so the dealership can add, edit and remove cars from the catalogue themselves, no developer needed.
