Fanny Salomon

Looking for a developer who can design a robust API, structure a reliable backend, or quickly understand a complex system?

I can help you develop your backend and web applications, with a particular focus on code performance, reliability, and maintainability. My goal: to deliver solid, tested, and scalable solutions.

Graduated from École 42, I have developed strong expertise in C/C++ and low-level systems (sockets, parsing, HTTP servers), which I now apply in modern web environments (Node.js, REST APIs, WebSockets). This dual skill set allows me to deeply understand how your applications work, beyond the frameworks.

What I can offer you:

REST API development (Node.js / Fastify)

Backend design and optimization

Real-time feature implementation (WebSockets)

Analysis, debugging, and improvement of existing code

Implementation of clean and scalable architectures

Security (JWT authentication, OAuth, 2FA)

What sets me apart:

A rigorous approach inherited from low-level programming (performance, memory, I/O)

A strong ability to understand and fix complex systems

A particular focus on testing, robustness, and edge cases

True autonomy and attention to detail

Types of projects / deliverables:

Complete backend APIs

Refactoring and optimization of existing code

Integration of authentication systems

HTTP servers / network services

Clear technical documentation

Critical bug fixes
