Senior Frontend Engineer (React / React Native) AI-assisted software engineering · Marseille, France

I build React and React Native products that keep working without a network, clear a full test pipeline before every release and stay observable once live. AI makes me faster; the engineering discipline around it keeps what ships dependable.

02 Case study · Petal

Petal: built for hospitals, where the network drops.

  1. the product

    Secure messaging and scheduling for care teams.

    Chats, shifts and night duties for care teams. I grew the React Native app and also contributed to the React web app.

  2. offline-first

    Airplane mode on. Work keeps going.

    Hospitals are full of dead zones. Every action is stored on the device first and syncs once a connection is back (Redux Toolkit, RTK Query, MMKV).

03 Experience

Four roles, each one shipped.

04 How I work

Fast with AI, safe by design.

tests · CI/CD · security

Every change passes a real pipeline.

Unit tests through Detox, Appium and Playwright E2E, with SonarQube and Trivy as gates on Bitrise and Jenkins. Auth0 and iXGuard / DexGuard harden the app, Sentry watches it live.

  • Jest · RNTL
  • Detox · Appium · Playwright
  • Cucumber · MSW
  • SonarQube · Trivy
  • iXGuard · DexGuard
  • semantic-release

AI, with guardrails

AI writes faster. The rules decide what is allowed.

Features start as OpenSpec changes. AGENTS.md and Cursor rules files give the model our architecture, conventions and test expectations, so generated code fits the codebase. Normal review and CI still gate everything. I wrote these guidelines for the team.
