About this gig

Is your API slow, insecure, or just not built yet?


I build production-grade REST APIs using ASP.NET Core that are secure, scalable, and ready for real traffic the same standards used in banking and financial systems.


Hi, I'm Daniyal a Backend Software Engineer with hands-on experience building production APIs for Meezan Bank and Alfardan Exchange. I don't just write code. I build systems that don't break under pressure.


WHAT I BUILD:

REST APIs with JWT + RBAC Authentication

ASP.NET Core Web API (Clean Architecture)

SQL Server / MySQL database design & integration

CRUD operations + error handling + logging

Postman collections for full API documentation
