Freelance Full-stack developer
Tracklab — Paris, FranceTracklab is the SaaS platform that reunite documents, quality constraints and suppliers. My mission was the migration from bubble platform to a full-stack platform in NodeJS with scalability in mind. This mission included: - Development of features, including the design of architecture, that are iso-functional with previous platform. Features included search views with cross-table filters and sorting, summary views, CRUD operations, CRONs operations and asynchronous data synchronization. - Connection to external APIs for data enrichment - Setup of test harness on the backend (end-to-end and unit tests) - Process improvement in order to provide more visibility and clarity to tasks
Co-founder & Chief Technology Officer
Sillant — Paris, FranceSillant is the new AI-powered SaaS platform that helps construction engineers reduce costs and errors when designing buildings. Entering as the CTO of an early stage startup, my objective was to reach the MVP as fast as possible. We underwent a lot of back and forth on the product with our prospects, and after first confirmations of interest, we settled on a verification and comparison engine for tender bids. This engine would ensure: - All bids respond to the construction work specification fully. Missing items are identified - Prices can be compared between identical items. A few of the challenges I had to overcome: - Table parsing from excel / pdf, including columns identification - Matching between identical items between tender bids to enable comparison - AI model deployments that would help in the matching (OCR, custom AI) - Reliable prompts (especially making them reliable and maintain them when OpenAI updated its models)
Co-founder & Chief Technology Officer
Toha Live — Paris, FranceToha is the new mobile and web app for second-hand fashion. Share your style and sell it through feed videos. Go live and meet your followers, give them some perks and engage them with auctions on your best pieces. As CTO and co-founder, I was responsible for product strategy and development. Some of the biggest challenges I faced: - Creating conference-like live architecture based on webRTC - Crafting a minimalistic and intuitive UI that enables the user the buy products while still being able to watch the live video on mobile devices - Implementation of PostHog and Sentry to enable fast and accurate iterations on the product - Implementation of Stripe integration for payments - AWS based infrastructure with automated deployments
Full-Stack Developer
Bloomflow — Paris, FranceBloomflow is the open-innovation platform that enables organizations to innovate efficiently with their partners on common projects. As a full-stack developer, I was responsible for designing and implementing key features, always prioritizing the end-user experience.
