About this gig

Is your production app throwing 500 errors? Are your Web APIs timing out or is Entity Framework dragging down database performance?


When enterprise systems fail, you need a Senior Backend Engineer not guesswork. I specialize in rapid dot net bug fix, C# debugging, and Node.js backend stabilization. I fix the root cause, so your system stays secure and stable.


WHAT I FIX:

  • ASP.NET Core Web API errors (500s, timeouts, CORS, JWT/OAuth)
  • Complex C# logic, async & multithreading bugs
  • Entity Framework (EF Core) & slow SQL query optimization
  • Node.js / Express bugs, crashes & memory leaks
  • Third-party API, webhook & payment integration errors


WHY ENTERPRISES TRUST ME:

  • Senior full-stack engineer (.NET, C#, Node.js)
  • Clean architecture & SOLID principles
  • NDA-friendly your code stays 100% confidential
  • Fast response & post-delivery support


Don't let backend errors cost you customers. Message me with your error logs and let's stabilize your system today :)
