About Tristan

Freelance web developer based in Lille since 2020, I support companies on concrete web projects, whether it's creating a website, evolving an existing application, or stabilizing a production environment.

My background has led me to work both as a freelancer, on showcase and e-commerce sites, and within more complex structures like Decathlon or Giphar. This dual experience has given me a very pragmatic approach to development.

As a freelancer, I design and deploy custom WordPress sites, often with WooCommerce, integrating existing mockups and going beyond simple theme configuration. I regularly intervene on advanced customizations, performance optimizations, and SEO. I also work with Symfony to develop more complex business features or backend logic adapted to client constraints.

In parallel, my current role as a technical production expert has taught me to manage sensitive environments.
I ensure the link between technical teams, users, and tools, by analyzing incidents, data, and usage to continuously improve products. This experience directly influences my freelance work approach: I always think "after going live".

I also have a solid background in backend and application maintenance.
This has taught me to be rigorous, to quickly diagnose blocking bugs, and to intervene without breaking the existing system.

Concretely, I work autonomously, with a real concern for understanding the needs. I am proactive, propose solutions, and place great importance on communication, especially with non-technical stakeholders.

I am available for website creation or redesign missions, specific development, maintenance, or technical reinforcement on existing projects, remotely or in Lille and its region.
