Gig Summary

About this gig

Is your ASP.NET application throwing errors, running slow or failing to deploy? I find the root cause, fix it properly and explain what changed.


I'm a full-stack .NET developer with 5+ years of experience, 40+ clients and 60+ projects delivered. I work with ASP.NET Core, MVC, Web Forms, C#, SQL Server, React and Next.js.


What I fix and build:

  • Runtime errors, crashes and broken features
  • Slow pages and SQL query performance
  • Login, JWT, OAuth and Identity issues
  • Upgrades from .NET Framework to .NET 8+
  • Deployment to IIS, Azure or AWS
  • API and third-party integrations, including OpenAI


How every order runs:

1. You share the issue, the code and steps to reproduce

2. I confirm scope and delivery date before I start

3. You get a progress update during the order

4. Delivery includes a short note: what was wrong, what I changed, how to test


Not sure which package fits? Send me the error message and I'll tell you honestly.


Bigger project or custom scope? Message me first and I'll send you a custom offer.
