    Paris, France
    Weezem is a mobile application available on iOS and Android that allows you to make new friends and find activities and outings.

    https://weezem.com

    I built the app and servers from scratch using React Native, Node.js, GraphQL, PostgreSQL and Google Cloud.
    Today, I still maintain the app and add new features.

    We launched the app in 2021, we now have 100k+ registered users and 1M+ messages in the messaging system.

    I also worked as a Product Owner: designing screens, receiving user feedback, prioritizing features, and determining what should be done and how.

    You can try the app to see more! Be sure to set your location to Paris to see the most content.

    Paris, France
    Taiji Remote is a Bluetooth-enabled device that enables hands-free bike navigation through its companion app.

    As CTO, I developed the device, mobile application, and backend infrastructure over the course of a year.

    I designed a miniaturized PCB featuring an nRF52 SOM, 6 IO, battery circuit and USB power.
    I then implemented the firmware using nRF Connect SDK.

    For the mobile app, I chose Flutter to meet demanding animation performance requirements.

    The backend uses Node.js with OpenAPI, PostgreSQL with PostGIS for geospatial data, and weekly OpenStreetMap ingestion for up-to-date cartography.
