Freelancer profile translated to English.
Back to original languageAbout Tristan
I design and develop custom business and SaaS applications, built to be robust, scalable, and used daily.
As an engineer and developer, I have delivered over 50 applications used in production by major groups (Crédit Agricole, Givaudan, Du Bruit Dans La Cuisine…), SMEs (Anaka, retail networks…), and startups, from the initial idea to structured teams and funding rounds.
What I build
- Business applications (internal tools, ERPs, dashboards)
- SaaS (subscription, user management, business logic)
- Custom web applications (Next.js, React)
Goal:Create useful, high-performing applications capable of supporting growth.
Approach
I work with a product mindset: prioritization, rapid iterations, and continuous improvement.
Each application is designed to be maintainable, scalable, and aligned with your business objectives.
Some experiences
Anaka (construction): construction planning reduced from 3 days to 1 day
Du Bruit Dans La Cuisine (40 stores): development of several internal tools
Crédit Agricole: 3 applications for international events, renewed each year
LibertéWatts: initial design then evolution → tens of thousands of users
My role is not limited to development: I design structuring tools that are actually used.
If you are looking for someone to transform a need into a concrete, reliable, and scalable tool, I would be delighted to discuss it with you.

Experience
- Wilden.studioIndependent Web and Mobile App DeveloperSOFTWARE PUBLISHINGNovember 2024 - Today (1 year and 7 months)Lyon, FranceCreate web and mobile applications that are accessible, both financially and in terms of ease of use, without compromising on quality or data security. This is made possible through innovative visual development technologies (no-code).What I do:
- Application Design:Light UX/UI touches if necessary to validate a visual direction and optimize user experience.
- Development:Transforming ideas into performant and reliable applications.
- Support:Personalized follow-up to ensure my clients' success.
Tools used:Bubble.io (expert), FlutterFlow, Make, Webflow, Xano… and many others (no-code technologies evolve quickly).If the project requires it:Next.JS - React - Node, ExpressDjango - FlaskReact Native, ExpoI am starting this new activity, but feel free to check out my previous experience at Lunicorn Studio for more details.--------------PS: I can also develop web services with Node/Express, Next.JS, Django (data projects), and front-end plugins with jQuery (Bubble plugins) or React (my favorite front-end framework), or even Next.js. However, this loses the advantage of visual development. That said, I can provide a strategic vision if you are considering scaling with a traditional stack for large-scale SaaS projects in the long term. - Lunicorn.StudioTechnical & Product Manager (CTPO)SOFTWARE PUBLISHINGOctober 2022 - October 2024 (2 years)Lyon, FranceWhat I accomplished:
