About this gig
Are you looking for a secure, high-performance backend for your application? Or do you need a seamless integration with a third-party service?
I am an experienced backend engineer specializing in the .NET ecosystem. I build robust RESTful APIs and seamless integrations that power modern web and mobile applications. Whether you need a brand-new API built with clean architecture, a critical bug fix, or a complex third-party integration, I deliver clean, documented, and maintainable code.
What I Offer:
Custom API Development: Building high-performance REST APIs using Dotnet Core and ASP.NET Core.
API Integration: Connecting your system with any third-party service (Payment gateways, CRMs, Twilio, Shopify, etc.).
Database Management: Integration with SQL Server, PostgreSQL, or MySQL using Entity Framework Core.
Interactive Documentation: Standard and premium packages include interactive Swagger or Scalar documentation.
Security: Implementing secure endpoints using JWT tokens, OAuth, or API keys.
IMPORTANT: Please contact me before ordering to discuss your exact requirements, budget, and timeline.

FAQ
What do I need to provide to get started?
Please provide a clear description of your requirements. For integrations, I will need the documentation or API links of the third-party service. For new APIs, a list of required features, endpoints, or data fields is highly appreciated.
Do you provide the source code?
Yes, absolute ownership. The complete source code repository is included with every delivery across all packages
What is included in a revision?
A revision includes bug fixes, minor tweaks, or adjustments to the originally agreed-upon requirements. If you need entirely new features or endpoints that weren't in our initial scope, that will be handled as a separate custom offer.
