Description

Full Stack Web & Mobile Developer for 10 years now, I have supported startups, SMEs, and large groups such as (Carrefour, DB Schenker, alinéa, Vinci Autoroutes…) in the design of tailor-made business applications that digitize and automate their activities.

My specialty: B2B platforms and business-critical management tools — e-commerce and marketplaces, logistics and delivery, order, inventory, and billing management, back-offices and client portals, dashboards, and real-time tracking.

Some achievements: the design of Fast-IT, an ecosystem of web and mobile delivery platforms (online ordering, real-time tracking, Stripe payment, geolocation) reused as a foundation for catering, food product sales (MedinaDeli), and spare parts distribution; as well as the maintenance and evolution of critical .NET Core APIs at Vinci Autoroutes (asynchronous processing, Kafka real-time streams, CI/CD).

My technical expertise: back-end .NET / C#, Node.js, PHP/Symfony; front-end React, Angular; SQL Server, PostgreSQL, Supabase databases; native Android/iOS and cross-platform mobile; API integrations, online payment (Stripe, PayPal), Docker, and CI/CD.

Goal: deliver reliable, scalable, and directly useful solutions for your business. Let's talk about your project.

Terms: assignments carried out remotely (100% remote), with regular video calls. Possibility of occasional travel to Marseille and its region if the project requires it.
