PROFILE

João

Over five months, contributed to roboflow/inference and roboflow-python by building and enhancing backend features focused on computer vision and data processing. Developed the GazeBlockV1 for gaze detection, integrating face detection, landmark handling, and prediction outputs, while refactoring utilities and expanding test coverage using Python and Pytest. Improved schema parsing by supporting complex Union and Selector patterns, strengthening type safety and reliability. Extended image format support in roboflow-python, adding TIFF, AVIF, and HEIC compatibility, and implemented hosted inference for text-image-pairs with flexible response handling. Maintained high code quality through documentation updates, code cleanup, and disciplined version control practices.

December 2024 monthly summary for roboflow/inference focused on delivering a robust Gaze Detection capability, improving workflow reliability, and strengthening validation coverage. Key work centered on the GazeBlockV1 core with face detection, landmark handling, gaze prediction, and yaw/pitch outputs; including refactors to outputs, conversion utilities, and workspace integration with a local execution fallback. Registry and configuration updates ensured correct model wiring and reduced conflicts, while expanded test coverage validated predictions, angles, and visualization within the workflow. These efforts collectively advance gaze analytics capabilities while reducing risk in downstream pipelines.
