Integrate the field (mobile data collection) into your existing IS (ERP, AS/400, SQL…)

🛠 What I do

Evolutionary & corrective maintenance of existing .NET applications

Creation of Web & desktop apps (ASP.NET Core, Razor/Blazor, C#, REST APIs)

MAUI mobile apps (iOS/Android) for field technicians: forms, photos, signature, GPS, offline

Dashboards & traceability (real-time, reporting, intervention tracking)

Occasional technical support (sprints, stabilization, backlog recovery)

📦 Commitments

Planned delivery, clean, tested, and documented code

Integration into your IS: I adapt to your context, not the other way around

Clear communication (email, Trello, Notion), high autonomy
