# Oliver Olejar

**Headline:** Professional profile
**Location:** Ontario, ON, Canada

## About

Oliver Olejar is an AI and machine learning practitioner with experience building agentic systems, leading technical club projects, and working across product and engineering\. Oliver’s strengths include combining system design with hands\-on development, translating user needs into practical technical solutions, and staying closely involved in implementation\. He has worked with vector databases, embedding creation, structured\-data extraction from PDFs, and AI safety testing, including handling out\-of\-scope queries and reducing hallucinations\. In internship work, Oliver gained hands\-on experience with agentic AI his machine learning experience also includes club and personal projects\. A notable project was an AI agent for robot\-maintenance troubleshooting that used vector databases and PDF embeddings to retrieve relevant information from documentation\. As a team lead on club projects, Oliver has taken responsibility for both architecture and development work\. His approach connects end\-user considerations with technically grounded product development, including pragmatic work with imperfect documentation data and difficult PDF\-retrieval challenges\.
