Custom business software in Valenciennes & Northern France
Management applications, internal tools and automation: .NET/C# software designed around your business rules, where generic products reach their limits.
The blind spot of local web agencies
Across the Valenciennes area and the Nord, there are plenty of WordPress studios and "showcase site" agencies. Great for an online presence. Far less so for the internal tool that manages your orders, syncs your stock or makes two systems that ignore each other talk. That is exactly where I come in.
Twenty years of .NET/C# development, much of it in data integration for retail and e-commerce. I build robust business software, connect your systems (ERP, marketplace, warehouse, accounting) and automate what wastes your time.
A single point of contact, based in Valenciennes, available on-site across the Hauts-de-France and remotely throughout France. No middleman between you and the code.
What I build
- Custom business software and internal tools (.NET / C#, ASP.NET Core)
- Management apps, WPF and Windows services
- Internal portals and workflows tailored to your teams
- Automated imports, exports and business processing
- REST APIs and system interconnection (ERP, PIM, accounting, warehouse)
- Migration and modernisation: .NET Framework to modern .NET
- Automation of repetitive tasks and takeover of existing code
Real engagements, not slogans
Centralizing a scattered process
Requests by email, approvals in a spreadsheet and manual tracking: I bring every step into one business application with permissions, notifications and an audit trail.
Modernizing a legacy .NET application
A critical application that is hard to evolve: I secure the existing system, decouple risky components and prepare a gradual modernization without a disruptive cutover.
Replacing a critical Excel file with a real tool
The shared file everyone opens, breaks and saves twice: I turn it into a reliable multi-user .NET application, with a database, permissions and history.
Automating repetitive tasks
Imports, exports, reconciliations, reports sent by hand every week: a .NET service that runs on its own, at night, and gives you hours back every month.
Why this niche, why me
Business software cannot be improvised. It requires .NET and architecture expertise, but above all an understanding of users, business rules and the exceptions that define day-to-day operations.
That is what I have done for 20 years, notably in retail. An internal tool to build, a process to simplify or an application to take over? Let's talk — the first conversation and the quote are free.
