Generative AI Architect at Altia building production RAG and multi-agent systems for business processes.

Spain

Message

At Altia, I design, build, validate, and move Generative AI solutions into production, from textual and multimodal RAG to multi-agent systems for business problems. I work across the process to make sure the result meets expectations.

Previously at Verne Technology Group, I worked on similar production solutions and developed an agent framework and multi-agent pipelines. At Maisa, I contributed to the KPU technology unit MVP, working on AI-agent and LLM research.

At Clibrain, I worked on Spanish-language models, LLM training and evaluation, and audio AI applications. Earlier, as a Junior Audio AI Engineer intern at Voicemod - We're Hiring!, I developed a real-time Speaker Style Classifier to distinguish sung from spoken language; I'm now researching how to make AI agents flexible yet auditable for critical processes.
