Freelancer profile translated to English.

Description

Since 2021, I've been helping startups with their technical choices, taking into account their business constraints and history. I help find the right balance between immediate effectiveness and future scalability.

Throughout my assignments, I have mentored over 10 junior developers to accelerate their skill development and improve the reliability of their deliverables.

Through my professional experiences and numerous side projects, I have a strong affinity for both backend and frontend, which allows me to have a global vision of the product, and total autonomy in designing the best solutions.

My current favorite stack:

✍️ TypeScript everywhere, which provides unprecedented peace of mind compared to Javascript.
⚛️ React with nice hooks, which elegantly encapsulates and decouples components, enhanced with some contexts and topped with Zustand.
🐈 NestJS on the backend, for building very good decoupled and testable services.
🔗 GraphQL for these last two to communicate quickly, flexibly, and efficiently.
💾 MongoDB / SQL to store your precious data.
🖥 AWS to run all of this.
