Full-Stack Mobile Developer

Dec 2025 - Present • 10 mos

I design and deliver end-to-end products: mobile apps, websites, backends, and deployment. Completed projects: • DuelFinder — a matchmaking mobile app for TCG players (Flutter, Node.js, PostgreSQL): Mapbox geolocation, messaging, FCM push notifications. Developed solo from start to finish and delivered to the client. • DevisRapide — Belgian platform connecting individuals with tradespeople on a pay-per-lead basis (Next.js, Prisma, Stripe): rechargeable wallet, matching by ZIP code, back office. • Plarya — premium sports analytics platform (Next.js, Node.js, Stripe): daily or subscription-based access. • Livepulp — refactoring and stabilization of an existing Flutter codebase. • Apogee Invest — pipeline for the automated aggregation and publication of financial news (Node.js, deployed on a Linux VPS). • Kairn.me, a web-based SaaS for knowledge retention powered by an LLM pipeline. • Trace, an app that teaches users to understand and evaluate code—including code generated by AI—rather than just memorizing syntax.
