Tudor Bordianu

Junior Developer

I discovered my passion for software engineering while working with data during an internship in Italy. Rather than focusing solely on development, I'm drawn to the broader engineering aspects of software building scalable systems from the ground up. I believe great software comes from understanding the entire picture, not just writing code.

Projects

Medical RAG

A RAG system for medical literature with fine-tuned embeddings. Scraped ~10,700 PubMed abstracts, mined hard negatives via BM25, and fine-tuned a sentence-transformer to distinguish similar clinical concepts. Uses hybrid retrieval (FAISS + BM25 with Reciprocal Rank Fusion), achieving +9.5% MRR improvement over the base model.

Solar & Heat Pump Advisor

A domain-specific Q&A assistant fine-tuned on German energy regulations, solar installation guidelines, and heat pump advisory data for Baden-Württemberg. Uses QLoRA fine-tuning on Mistral-7B with a curated dataset of 2,500+ Q&A pairs, achieving 78% domain accuracy and reducing hallucinations to 8%.
