I’m a Full-Stack Developer who naturally gravitates toward the backend — not just writing code, but understanding why systems behave the way they do and how to make them faster, cleaner, and more scalable. Most of my experience revolves around building backend-heavy applications with ASP.NET Core, SQL Server, and Angular, often working on complex platforms like ASP.NET Zero. Over time, I became especially interested in architecture decisions, performance optimization, caching strategies, and applying design patterns to keep systems maintainable as they grow. What motivates me most is impact: simplifying complex workflows, improving system performance, and helping teams make better technical decisions. I enjoy reviewing code, supporting other developers, and thinking beyond implementation toward long-term scalability and reliability. I’m also deeply curious about AI integration — particularly LLMs, RAG, and NLP. While my hands-on experience is still growing, I actively explore these areas through projects and learning, driven by a strong desire to evolve and adapt. I’m someone who learns fast, takes ownership, and enjoys building systems that make sense — both for users and for developers who will maintain them tomorrow.
