Rising Talent
Project details
Are you building a backend system and need a reliable, scalable .NET Core REST API? I specialize in designing and building production-grade REST APIs using ASP.NET Core, C#, Entity Framework Core, and SQL Server, following clean architecture principles.
What you'll get:
• Fully functional REST API with CRUD endpoints and business logic
• Clean Architecture structure (Controllers, Services, Repositories, Domain)
• JWT authentication and role-based authorization
• Entity Framework Core with SQL Server migrations
• Swagger/OpenAPI documentation
• Input validation, error handling, and logging
• Unit tests for key business logic
• Source code delivered via GitHub or ZIP
Whether you need a simple CRUD API or a complex multi-module backend system with integrations, I build it with scalability and maintainability in mind. My APIs follow SOLID principles and REST best practices, making them easy to extend and maintain.
From small startups building their first MVP to businesses scaling their SaaS platform, I deliver clean, well-documented APIs that your frontend team will love working with.

I am reaching out regarding a semi-automatic trading strategy I had developed for MultiCharts.NET
Asad is, above all, a very serious and competent person, used to completing his work successfully. Punctuality is guaranteed — if he says “let’s talk at 7 p.m.,” you can be sure he will. Professionally, he accomplished a very complex task that many other professionals had described to me as impossible to achieve due to the limitations of the MultiCharts.NET platform. He programmed the script, tested it, and after a week of intensive use, everything works perfectly. We already have other projects in development, and Asad will certainly take care of them. For the quality of the services he provides and the way he delivers them, he should really charge a higher fee. Thank you, Asad.
