About this gig

Need a high-performance, secure, and scalable backend for your mobile or web app? With 15 years of experience in the .NET ecosystem, I specialize in architecting robust RESTful APIs that follow industry best practices.


Whether you need to integrate a payment gateway, a CRM, or build a custom API from scratch, I ensure your data flows securely and efficiently. I don't just build endpoints; I build production-ready systems with full documentation.


What I offer:

  • Custom API Development: ASP.NET Core Web API (C#).
  • Expert Integrations: Stripe, PayPal, Twilio, SendGrid, Google Maps, Salesforce, etc.
  • Security First: JWT Authentication, OAuth2, Identity Framework, and API Key protection.
  • Database Integration: Entity Framework Core with SQL Server optimization.
  • Documentation: Interactive Swagger/OpenAPI documentation included.
  • Architecture: Clean Architecture, Repository Pattern, and Dependency Injection.


Why hire a Senior API Expert? In API development, security and performance are non-negotiable. I write clean, maintainable code that prevents common vulnerabilities and handles high traffic with ease.
