Shipped mobile apps, marketplaces, and client-facing tools — things users actually touch.

Xyste

Couples & wedding vendors

Two-sided marketplace with tiered subscription monetization. Vendor discovery, messaging, booking — the full loop. Applied to weddings. On the App Store.

The hard part of marketplaces is making both sides show up. Vendor onboarding, search + filtering, in-app messaging, booking flows, and three subscription tiers (€4.99–€119.99/mo). React Native + Supabase. Submitted to the App Store.

OBD2 App

Independent mechanic

Plug in a $20 adapter, ask a question in plain English, get an answer a mechanic would give. AI that reads hardware.

Most diagnostic tools show cryptic codes. This one has a conversation. The app reads live OBD-II sensor data, an LLM cross-references 24,169 diagnostic codes across 19,027 vehicle configurations, and explains the fault in context — not just "P0420", but what it means for your specific car, what caused it, and what to do. The architecture (read → analyze → explain) generalizes to any hardware-to-AI bridge.

SwiftUI Component Library

Mobile development agency

The design system behind every iOS product. 140 components, 25 categories. Build a new screen in hours, not days.

Every app we ship (Xyste, OBD2, OnePilot) pulls from the same component library — 140 production-grade SwiftUI components across 25 categories. Navigation, forms, inputs, cards, modals, loading states — consistent, tested, reusable. New features compose from existing pieces. The library grows with every product, and every product benefits from improvements to the library.

Taxi Cooperative Website

Taxi cooperative

A local business needed to exist online — not a template, but a site that actually converts. Multi-city SEO, fleet showcase, pre-booking. Live and ranking.

A 35-vehicle taxi cooperative in Burgundy needed a web presence that actually drives calls — not a generic template. Built with Astro for near-zero JS, with dedicated SEO-optimized pages for each city (Auxerre, Joigny, Chablis, Tonnerre), fleet showcase, service descriptions (airport transfers, CPAM medical transport, tourism), and a pre-booking flow. Static site, fast on any connection, ranking on local search. Real client, live in production.
