About Victor

Full-Stack & Mobile Developer | Expert Business Solutions (EBP / Batigest)
Need a high-performance application, a tool connected to your management system, or a robust network infrastructure? I help companies create tailor-made digital solutions, from design to deployment.

My difference: The connection between your management and your tools
Where many stop at the website, I go further by connecting your applications directly to your management databases (EBP, Batigest/Sage). My goal: to automate your processes to save you precious time.

My areas of intervention:
Web & Mobile: Development of modern interfaces with React and high-performance native mobile applications (Swift for iOS, Kotlin for Android).

Business Software: Creation of gateways and tools connected in real-time to your databases (SQL Server, PostgreSQL).

Infrastructure & Network: Configuration of NAS servers, preparation of IT equipment, and implementation of secure tunnels (Cloudflare) for your local services.

Why work with me?
With a background combining technical support at La Poste (DSEM) and work-study development at Présence Informatique, I blend methodological rigor with technical agility. I don't just deliver code; I ensure your solution is hosted, secure, and fully functional.

Let's discuss your project to transform your technical needs into growth tools!
