Senior Data Scientist @ Ono AI Based HR Platform

About

I’m a Senior Data Scientist focused on Applied AI and LLM systems. My background combines mathematics, programming, and hands-on experience in building AI solutions that solve real business problems. I have worked on machine learning and deep learning projects, and more recently I have been focused on end-to-end applied AI systems, designing and delivering production-ready solutions for real-world business problems. I don’t just prototype ideas, I turn them into production-ready systems. My focus is on designing practical AI solutions and delivering reliable applications for real business needs. I’m especially interested in applied machine learning, LLM applications, and building practical AI systems that create measurable value.
