Alex’s strengths include multi\-agent orchestration, retrieval\-augmented generation, edge\-oriented pose\-estimation deployment, cloud automation, and security\-first agent design\. At VigilantAI, Alex built a computer\-vision pipeline for more than three months of multi\-camera CCTV footage, combining motion filtering, person detection, and 3D pose estimation to achieve more than 97% keypoint\-extraction accuracy for downstream anomaly detection\. Alex also benchmarked YOLOv8 pose estimation against NVIDIA BodyPose3DNet and achieved real\-time 30 fps inference across concurrent 720p camera streams\. Previously, at CSX Technology, Alex architected an agentic workflow for self\-service file recovery and backup that reduced costs by 90% and shortened turnaround from three days to under five minutes\. Alex holds both a Master’s degree and a Bachelor of Science degree in Computer Science from Virginia Tech\. Alex is seeking larger\-scale, more technically complex challenges and is open to remote, hybrid, or in\-office work arrangements\. ## Highlights - Built a computer\-vision pipeline at VigilantAI processing more than three months of multi\-camera CCTV footage with motion filtering, person detection, and 3D pose estimation, achieving more than 97% keypoint\-extraction accuracy for downstream anomaly detection\. -
