Oliver Olejar

- Leading a 5-member interdisciplinary team to develop an electrocardiogram (ECG)-based sleep-apnea screening tool; research paper underway for the Canadian Undergraduate Conference on Artificial Intelligence (CUCAI). - Architecting a TensorFlow pipeline with CNN-Transformer components; achieved 91% validation accuracy and AUROC 0.97 for predicting apnea events from ECG. - Developing an explainability agent for clinician-facing insights using Grad-CAM heatmaps and features such as heart rate variability (HRV) to support interpretable results.

- Lead a software team of 10+ and partner with mechanical and electrical teams to build a smart ACL-rehab knee sleeve. - Design an Arduino-driven EMG/IMU sensor pipeline from capture and sync to feature-ready datasets. - Architect the ML stack and evaluation roadmap for recovery-time model prediction (problem framing, labels, features, model selection criteria). - Maintain a clean repo and contribution flow (branches, PR reviews, issues, venv/requirements, pre-commit/CI). - Run hands-on workshops on Python data/ML libraries (NumPy, pandas, SciPy, matplotlib, scikit-learn) and Git/GitHub; onboard contributors and standardize workflows. - Hosting the inaugural True North Biomedical Competition at Western University.

- Built an MVP multi-agent AI maintenance assistant for robot technicians (vector-database RAG, OpenAI Agents SDK, Langfuse); retrieves procedures, error-code context, and prior fixes, and auto-generates maintenance reports. - Designed a data pipeline that ingests Microsoft Planner tasks via Microsoft Graph API and Power Automate, stores in SharePoint, and visualizes progress in Power BI (Milestone Heat Map), automating a 90 min manual update. - Deployed Moodle for an employee training program on a LAMP stack (Linux, Apache, MySQL, PHP), integrating SCORM modules and custom themes; centralized training, onboarding, and content publishing on one platform.

- Primary point of contact for the IT department; triaged walk-ins and service-desk tickets, achieving over 80% first-contact resolution (FCR). - Imaged and configured Windows workstations using registry baselines and Group Policy, ensuring reliable deployments across 3+ manufacturing lines. - Administered Active Directory (account provisioning, groups, permissions) and enforced USB and device controls via Linamar's security platform to maintain access hygiene and endpoint integrity.
