About

.NET Core Backend Developer | API Development, Scalable Architecture & Integration | UI-Ready (Blazor/Angular)

Dear Client,

I'm a backend-first .NET Core developer with a strong focus on building scalable, reliable, and well-structured systems. My core expertise lies in API development and integrating with complex third-party platforms, particularly in finance, POS, and automation domains.
I’ve successfully worked with platforms such as:
- QuickBooks – Financial/accounting automation
- Railz & Qodat – Financial data aggregation
- Clover – POS and transaction systems
- Avalara AvaTax – Tax compliance and automation
- Along with custom APIs involving OAuth2, webhooks, and real-time messaging workflows

I design modular backend services using ASP.NET Core, Entity Framework, and SQL Server — ensuring long-term maintainability, high performance, and clean separation across services, domains, and infrastructure. I prioritize practical scalability and clear architecture tailored to each project's real-world needs.

While backend is my specialty, I’m also experienced with Blazor and Angular, which enables me to contribute to frontend development when needed for full-stack delivery.

🔧 **What I Bring:**
- Robust API development (RESTful, secure, well-documented)
- Smooth integration with enterprise platforms
- Scalable, layered backend architecture
- Clean data modeling and business logic organization
- Professional communication and reliable delivery

If you're looking for someone who understands the technical depth **and business impact** of well-architected backend systems — let's connect.

Sincerely,
Osama Younus
.NET Backend Developer | API Integration Specialist | UI-Ready (Blazor/Angular)
