Available to hire
I am Maryna Bogdan, an AI/LLM engineer based in Vigo, Spain, with 6 years of experience in NLP and 2 years in Generative AI. I build real-time applications powered by LLMs, focusing on prompt engineering, retrieval-augmented generation (RAG), and agent-based workflows.
I design end-to-end solutions, deploy functional prototypes, and align AI systems with business needs. I have a strong foundation in applied linguistics, model integration, and cross-functional collaboration.
