About this gig

I am a senior .NET developer with 18+ years of experience building scalable, secure, and production-ready applications.

I can help you develop or improve ASP.NET Core Web APIs, backend applications, database-driven systems, and third-party integrations using clean and maintainable architecture.

My services include:

  • ASP.NET Core Web API development
  • REST API design and development
  • C# and .NET backend development
  • SQL Server and database integration
  • Third-party API integrations
  • Authentication and authorization
  • Clean Architecture and SOLID principles
  • Dependency Injection and service-based architecture
  • Logging, validation, and error handling
  • Existing API troubleshooting and performance improvements
  • Legacy .NET application modernization
  • Unit testing and code review

I have extensive experience working on enterprise and business-critical applications and focus on writing clean, maintainable code rather than simply delivering something that works.

Please contact me before placing an order so we can discuss your requirements, complexity, and the appropriate package.

For complex applications, integrations, or long-term development, I can also provide a custom offer.
