About Antoine

Product-oriented full-stack developer, I design robust web and mobile applications, with a particular focus on architecture, typing, and maintainability.

Web -I mainly developAPIsand applications withNode**. I have good experience with the **Expressframework and tend to steer my new projects towardsNestto strengthen architecture and industrialize quality. Comfortable withReact**, I prefer **Nextto frame the project and accelerate delivery. Typing being key for stability, I useTypeScriptacross the entire web stack.

Mobile -I developed and maintained Vize inFlutterfor just under two years, implementing my firstclean architecturethere. To achieve an audio latency of less than 10 ms, I developed the application's audio engine inC++with communication viaFFI**. I also developed a small solution in **Swiftto easily import my running sessions onto my Apple Watch.

Infra -Maintenance and deployment of projects onOVH**, **GCP**, and **DigitalOceanwithDocker**, automated deployments and storage via buckets, as well as distribution of mobile applications via **TestFlight**, the **App Store**, and **Firebase(Android beta).
