About this gig

Need your systems to talk to each other? I build reliable API integrations and backends in .NET / C# that connect your apps, automate data flow, and just work.

I'm a systems analyst with years of real-world experience integrating enterprise systems, ERPs, and third-party APIs. I handle the full cycle from understanding the business need to delivering clean, production-ready code.

What I can do for you:

  • Integrate third-party REST APIs into your application
  • Build custom REST APIs and backends (.NET / C#)
  • Connect systems, ERPs, e-commerce and marketplaces
  • Automate data sync between platforms
  • Database integration and persistence (SQL)

Why work with me:

  • I understand the business problem first, then build
  • Clean, documented, maintainable code
  • Secure authentication (OAuth, tokens, API keys)
  • Clear communication and on-time delivery

Not sure how to scope your integration? Send me a message with what you're trying to connect I'll tell you exactly what's possible. Let's build it!
