Looking for aFullstack Developerwho delivers clean code, scales in production, and doesn't come back with surprises two weeks later?
That's exactly where I come in.
AnENSIIEengineer with5 years of experiencein theJavaScript/TypeScriptecosystem, I've worked on technically challenging projects: a wealth management simulation FinTech platform at Apptitude SA, high-volume internal tools for Crédit Agricole (reducing memory footprint by 40% on an export engine), and multi-platform desktop applications at SYSTRAN, a world-leading translation company.
My main stack:
React, NextJS, NestJS, Node.js, TypeScript, PostgreSQL (Prisma, Mikro-ORM).
I master the entire cycle — architecture design, development, testing (Jest, Supertest, SonarQube), CI/CD, and API documentation (Swagger/OpenAPI).
What sets me apart today: I integrate AI tools directly into development workflows. I've implemented aSpec-Driven Developmentmethodology with AI agents (Cursor, Claude Code, Kiro.dev) that significantly accelerates delivery cycles. I've also explored RAG architectures withWhisperandHuggingFacein personal projects.
I am available for remote or on-site missions, short or long term.
