Back to original languageAbout Nicolas
Hello,
Here is my ever-evolving portfolio:
About my background:
I design and develop mobile applications and business tools, combining product thinking, API integrations, and applied AI.
After 10+ years in tech project management in demanding environments (Google France, Orange, Fnac/Darty, LVMH, Dior, Hermès, Luxottica), I am now focused on designing and developing useful digital products, with a solid product approach and hands-on execution.
I am currently developing Tickount, a mobile expense management application built in React Native / TypeScript, designed to simplify accounting for freelancers and SMEs. Proof scanning, structured data extraction by AI, local persistence, cloud synchronization, accounting exports (XLSX + FEC compliant with LPF). Zero-Trust architecture with serverless proxy to secure the AI key, true offline-first, isolated multi-cloud sync by provider.
In parallel, I am building AI-assisted visual workflows (image-to-image, image-to-video) that enhance existing assets without betraying the artistic direction.
My background gives me a hybrid perspective:
> product and business understanding
> tech, design, and stakeholder coordination
> ability to structure, prioritize, and advance a project
> hands-on execution on mobile apps, API integrations, and application logic
What particularly interests me:
> B2B and B2C mobile apps
> internal business tools
> API and cloud integrations
> AI-assisted workflows
> product-oriented development
