I'm an early-career Backend Developer focused on building clean, reliable server-side systems with C# and ASP.NET Core. I've designed and implemented RESTful APIs from scratch, built relational database schemas with Entity Framework Core, and handled authentication, validation, and business logic in a full-stack thesis project using Clean Architecture.

I also have hands-on experience with Java / Spring Boot through a second full-stack project, and I completed a remote Front-End Developer co-op where I worked in an Agile team, integrated third-party REST APIs, and used Docker in the development workflow.

What I can help you with:
- RESTful API development using ASP.NET Core (.NET 8)
- Database design and SQL (SQLite, PostgreSQL, SQL Server)
- Backend business logic, JWT authentication, and API integration
- Bug fixing, debugging, and code cleanup in existing C#/.NET projects

Tech I work with daily:
C#, ASP.NET Core, Entity Framework Core, SQL, Git, Docker, Postman. I also use AI coding tools (ChatGPT, Codex, Claude Code) for debugging and code review.

How I work: I ask questions before I start, communicate clearly, and deliver code that's structured and documented. I'm early in my career, which means I'm responsive, motivated, and priced fairly for the quality I deliver.

If you need a backend developer who can take a database schema and build a working API around it, I'd love to hear about your project.
