Freelancer profile translated to English.
Back to original languageAbout Tristan
I design and develop business applications (Bubble in particular) to structure and automate the operations of companies, SMEs, and startups.
An engineer and developer by training, I have delivered over 50 applications used in production by large groups (Crédit Agricole, Givaudan, Du Bruit Dans La Cuisine…), SMEs (Anaka, retail networks…), and startups, from the idea stage to structured teams and growth phases.
What I build
Business applications and internal tools
Management tools (ERP, workflows, team coordination)
SaaS platforms (subscriptions, payments, marketplaces)
Automations and integrations
These tools enable you to:
coordinate teams, clients, and partners
structure business workflows
centralize data and documents
automate operational processes
Goal: quickly deliver a first useful version, test it in real conditions, and then evolve it.
Experiences
Anaka (construction): construction planning reduced from 3 days to 1 day, for several dozen projects per year
Du Bruit Dans La Cuisine (40 stores): development of several internal tools (11 projects by early 2026)
Crédit Agricole: 3 applications for international events, renewed each year
LibertéWatts: no-code design then evolution to a more advanced stack, tens of thousands of users today (TF1, BFM Business…)
My role is not limited to development: I design useful, used, and scalable tools, aligned with your business challenges.
If you are looking for someone to transform a need into a concrete and reliable tool, I would be delighted to discuss with you and support you in the long term.
