Level 2
Gig Summary
About this gig
Need a .NET backend that holds up in production?
I build ASP.NET Core Web APIs, integrate payment gateways and third-party APIs, and fix backend problems other developers left behind. 13+ years, 36 five-star reviews, zero cancellations.
WHAT I BUILD
- REST APIs in ASP.NET Core (.NET 6/7/8/9) - clean architecture, JWT auth, Swagger docs
- Third-party integration - payment gateways, SOAP/XML, webhooks, CRM and verification APIs
- Entity Framework Core - data modelling, migrations, query and performance fixes
- SQL Server - schema design, stored procedures, slow-query tuning
- Azure - App Service, Database, CI/CD, custom domains and SSL
- Legacy rescue - MVC, WebForms and .NET Framework upgrades to .NET Core
RECENT WORK
Payment gateway integrations for Gulf and Iraqi processors, a South African screening platform wired into government registry SOAP services, WhatsApp OTP systems, and PDF reporting engines.
HOW I WORK
Scope confirmed in writing before I start. A progress update mid-project. Support after delivery. That is why I am still 5.0 after 70 orders.
Message me your requirement and I will tell you honestly if it is a fit and what it will cost, before you order.
