Backend Developer | .NET Core & API Specialist | Building Scalable, High-Performance Solutions

Hi, I'm Hossam — a Backend Developer with a passion for building robust, scalable web applications that solve real business problems.

I specialize in .NET Core, C#, and modern backend architecture. Over the past 6+ months, I've worked on production systems serving real users, where I cut API response times by 99%, built multi-tenant platforms with Clean Architecture & CQRS, and integrated real-time features using SignalR.

What I bring to the table:
- Strong foundation in .NET Core, ASP.NET Web API, and Entity Framework Core
- Database design and optimization (SQL Server)
- Cloud deployment experience with Azure services
- Real-time systems with SignalR (notifications, tracking, live updates)
- Third-party API integrations (authentication, payments, cloud storage)
- Performance-first mindset — I optimize for speed and reliability

Before backend development, I worked on AI research at Nile University, where I built ML pipelines serving 5,900+ students. This background gives me a unique edge in implementing intelligent features and data-driven solutions.

I also contribute to open source projects like InVesalius3 (medical imaging software), where I've refactored core logic and improved code quality with type safety.

I'm a problem solver at heart. I don't just write code — I take ownership of projects from start to finish, debug complex issues, and deliver clean, maintainable solutions. I work independently, communicate clearly, and always meet deadlines.

Currently pursuing my B.Eng in Computer Engineering at Mansoura University (87% GPA) while building real-world experience.

Let's work together to bring your project to life!
