I built a distributed bookstore backend with ASP.NET Core, separating catalog, authentication, and order processing into services. RabbitMQ supports asynchronous communication, while Ocelot handles API routing and centralized authentication.

For a healthcare appointment API, I implemented JWT authentication with refresh-token rotation and role-based access control. I added caching and monitoring, and wrote 197 passing xUnit tests.

In my freelance development work, I built a Windows POS and financial management system using WPF, ASP.NET Core, and SQLite, with an offline-first local data layer. I also developed custom Shopify storefront features that eliminated paid third-party integrations and reduced recurring SaaS costs by $50 per month.

At Commercial International Bank (CIB), I gained exposure to retail banking operations and explored digital banking, AI and machine learning, data analytics, and cybersecurity. I’m ready to contribute practical backend solutions, grow through real-world challenges, and learn through mentorship.
