PROFILE
Simon Schölly
Over six months, contributed to the lightly-ai/lightly-train repository by building and refining features for computer vision workflows, focusing on ONNX export reliability, segmentation performance, and dataset interoperability. Leveraged Python and PyTorch to implement dynamic batch size support, JSON-based label parsing, and robust model export verification, addressing both object detection and segmentation use cases. Enhanced data pipelines by supporting COCO and YOLO formats, introduced Jinja2-based training configuration, and improved dependency management for smoother deployments. Emphasized maintainability through improved documentation, automated checkpoint handling, and comprehensive testing, resulting in more flexible, scalable, and production-ready machine learning and deep learning pipelines.
