I will build a backend API using aspnet sql server or postgresql


About this gig
Need solid, reliable backend logic for your website or app? I build backend systems and APIs using ASP.NET (C#), connected to SQL Server or PostgreSQL databases designed to be secure, structured, and easy for any frontend to connect to.
I've built backend systems for several projects, including a full ecommerce platform (ASP.NET + Next.js) and management systems handling real data operations like bookings, orders, and records so I understand not just how to write backend code, but how to structure it properly for real-world use.
What I offer:
RESTful API development with ASP.NET (C#)
Database design & integration (SQL Server, PostgreSQL)
Authentication & authorization systems
CRUD operations (create, read, update, delete) for your data
Business logic implementation (orders, bookings, records, etc.)
Clean, documented endpoints ready for any frontend to connect to
Why work with me:
- Built on solid fundamentals: OOP, Design Patterns, SOLID Principles, Data Structures
- Real project experience not just tutorials, actual working systems (ecommerce, hotel management, reservation systems)
- I write code that's structured to scale and easy for other developers to read
- Clear communicator I'll co

Yes, I can build authentication/authorization systems as part of your backend.
