    My curiosity about software development keeps growing. From the first idea to the final product, I'm captivated by the process of bringing things to life. At Calibre Tour, I work with .NET, PostgreSQL, Express.js, MySQL, and Next.js to build robust systems across both frontend and backend. On my own, I'm building LIBRAIN—an open-source multi-agent RAG system in .NET 10 that ingests scientific papers, embeds them in a vector store, and generates citation-grounded hypotheses through a Reader → Synthesis → Evaluator pipeline. It's a deliberate exploration of production-grade AI engineering on the .NET stack — combining Anthropic Claude, OpenAI embeddings, and Qdrant vector search. My focus: clean backend systems where .NET and AI tie together.
