Senior🎓
Top SchoolDeyan Yotsov is an AI engineer based in Budapest with nearly two decades of software development experience and over a decade focused on data and ML systems, including three years in team leadership. He builds production-grade LLM solutions (RAG, agentic RAG, semantic chunking) and scalable data pipelines that handled up to a trillion events per month, combining backend, ML and MLOps expertise. At Raiffeisen and Comscore he developed agent frameworks, improved RAG testing and delivered an internal 1M-chunk retrieval tool using pgvector and modern LLMs. Comfortable across the stack, he has hands-on experience with Spark, Kafka, Trino, AWS, and CI/CD for ML, and has led training and ISO 27001–compliant projects. Notably, he has repeatedly shipped end-to-end products—from a contracts search engine as a solo founder to enterprise chatbots—bridging research and production.
