About Elliot

Full-stack developer specializing in Node.js / NestJS and React / React-Native, I undertake high-value-added missions requiring speed of execution, technical reliability, and complete autonomy.

I primarily assist companies and startups with:
  • Developing robust and scalable APIs (Node.js, NestJS),
  • Creating and optimizing web and mobile applications (React, React-Native, Expo),
  • Real-time and IoT projects (Kafka, Modbus, industrial data),
  • Rapid deployment in containerized environments (Docker, cloud).
My approach is resolutely results-oriented: quickly understand business challenges, propose a clear architecture, deliver clean, tested, and maintainable code, and then secure the production deployment.

Accustomed to working on critical projects, I am comfortable with:
  • Short and intensive missions,
  • Targeted technical overhauls,
  • Developments from scratch.
I prefer collaborations where an operational developer is expected from day one, capable of making technical decisions and meeting deadlines.

Objective: deliver immediate value, reduce technical risk, and accelerate product delivery.
