About Thibault

Senior backend developer (9 years), I design and evolve robust applications and architectures that can handle load: from legacy to modernize to products built from scratch.

My core business: PHP/Symfony and Node.js/TypeScript, with a real culture of architecture (hexagonal, microservices, REST API) and a hybrid dev + infra profile (Docker, CI/CD, certified AWS Cloud Practitioner, RabbitMQ, Redis).

I have led fundamental migrations (Symfony 5 to 6, PHP 7 to 8), led teams as a lead, and delivered critical services with a focus on performance and observability thanks to Datadog and Sentry.

What sets me apart: I also build complete systems solo.
KraknTrade, my crypto portfolio management automation platform (and xStocks) developed entirely in Node.js/TypeScript, illustrates my ability to take a product end-to-end: from the data model to exchange integration to deployment.

Specifically, I can help you: modernize an existing codebase without breaking production, design scalable APIs and architectures, make a backend reliable and fast, or strengthen a team on a specific topic.

Available full remote, in French or English.

Clear communication, commitments kept, tested code.

    My experience as a freelancer at Eres positions me as a backend developer specializing in PHP/Symfony. My role covers both 'legacy' projects and new projects, where I have managed transitions from Symfony 5 to Symfony 6, PHP 7 to PHP 8, and from an MVC architecture to a hexagonal architecture.

    My integration at Eres was to provide support where specific needs arose. My ability to quickly adapt to the context and my flexibility are assets that I highlight.

    December 2021 - June 2023 (1 year and 6 months)
    Paris, France
    Joining the company from its inception as Lead Developer, I initiated the formation of a team of 3 developers for the web and web 3 sectors. I played a crucial role in designing the Smart Contracts for the sale of our NFTs, as well as developing a web platform with a social network focus, allowing NFT holders to showcase them in a 3D environment (the development part was handled by another team).

    Additionally, I managed the servers (dedicated and Google Cloud) for our various projects. We conducted numerous parallel POCs to test various features for integration into our platform.

    Following a change in the company's direction, from a B2C to a B2B focus, I decided to leave and become an independent contractor.
