About Benjamin

Fullstack developer since 2021, I design web and mobile products from A to Z: needs assessment, architecture, development, testing, deployment, and monitoring.


The best proof of what I can do is Quokalm, a mobile application that I imagined, developed, and published alone on the App Store and Google Play Store. It helps neuroatypical people find quiet places around them. Behind the app, there's everything that makes a real product: React Native and Expo on the mobile side, Supabase and PostgreSQL on the server side, a Mapbox map, translation into five languages, monetization through advertising and subscriptions, not to mention legal pages and GDPR compliance. I also designed and deployed a SaaS management tool for microbreweries, hosted on a server that I administered and monitored myself.

Part of my speed comes from my way of working with AI. I use Claude daily as an accelerator: I frame the need, break down the work, delegate what can be delegated, then I review, test, and validate everything that goes into production. I remain the architect and guarantor of quality; AI saves me the time of repetitive tasks. The result: faster deliveries, with no hidden debt behind them.

In parallel to my projects, I work for large companies. Currently on a mission for Société Générale, I am independently developing an insurance subscription journey in a micro-frontend architecture, in daily contact with business teams.

I work exclusively remotely, from Tours. This is a way of working that I have practiced for years and in which I have proven myself: autonomous, reachable, clear in my communication, and I deliver what is planned.

If you are looking for someone capable of taking your project from the first mockup to deployment, let's talk.

    Quokalm helps neuroatypical people find quiet places around them. I carried the project alone, from idea to publication on the App Store and Google Play, with already about fifty places listed in France.

    It's also the project where my work method with AI is best expressed: I orchestrate Claude on development to maintain a delivery pace that a solo developer wouldn't achieve, while keeping control of the architecture, code review, testing, and security.

    Specifically:

    • React Native / Expo application in strict TypeScript, React Navigation navigation
    • Supabase Backend: PostgreSQL with PostGIS for geolocation, authentication, RLS security rules on all tables
    • Interactive Mapbox map with place search
    • Full internationalization in 5 languages (French, English, Spanish, Portuguese, Italian)
    • Monetization: AdMob advertising and premium subscription via RevenueCat
    • OTA builds and updates with EAS (Expo Application Services)
    • Legal pages, privacy management, and GDPR compliance
