About David

I design custom business applications, from requirement to production. With fifteen years of experience and a background in graphic design, I combine technical expertise and design sensibility to create tools that meet user needs.

How I work
When you entrust me with a project, you get someone who handles the complete front-end architecture, creates functional and aesthetic interfaces even without a creative team, and delivers an operational application in production. My analytical mindset and ability to quickly acquire new skills allow me to adapt to new technical or business domains according to your needs.

My background makes the difference
My journey from graphic designer to developer allows me to communicate effectively with creative teams while understanding technical constraints. I design the complete interface, ensuring visual consistency, ergonomics, and accessibility. This dual skill reduces friction and improves the user experience.

My technical stack
I master the modern front-end ecosystem. As an independent developer creating my own products, I also touch upon back-end, infrastructure, deployment, and am passionate about AI and its design. I can challenge technical decisions, propose architectural improvements, and train teams if necessary.

Projects that interest me
I fully invest myself in projects where I am trusted with autonomy. Whether it's an established company looking to create complex internal tools, a startup needing to structure its front-end, or a team seeking someone to lead the creation of a new application.

If you are looking for someone who takes responsibility, delivers results, and is invested in your project, let's discuss it ;)

    PRESS AND MEDIA
    April 2022 - January 2025 (2 years and 9 months)

    Ouest-France, part of the SIPA group, entrusted me with another mission within their editorial department. I worked on numerous projects dedicated to our journalists and the smooth operation of the newspaper, including evolutionary maintenance and the creation of several key management and editorial assistance tools.
    In parallel, I collaborated for several months with 20 Minutes (SIPA) on the improvement and evolution of a live event management application, where I held a full-stack developer role with Node.js, React, and GraphQL.
    As the lead front-end developer for the team, I was proactive in suggesting improvements to the graphical interfaces, earning the trust of the teams to redesign some of them. Periodically, I trained my colleagues in Vue.js and contributed to the creation of a mutual support community within the newspaper to strengthen front-end best practices and skills within the organization.

    November 2021 - February 2022 (3 months)
    Nantes, France
    At Local.fr, a digital communication agency, I developed an application to centralize their numerous clients, domains, and hosting services. Faced with very specific needs that the native interfaces of OVH, Salesforce, and other tools did not meet, this solution was particularly strategic for them. I designed the user interface with VueJS and collaborated with an external team for the back-end in Symfony, ensuring perfect integration. This project effectively addressed their constraints and optimized their daily management.
