What I'm looking for

I seek remote roles in computer vision or AI data annotation, with collaborative teams, clear QA standards, growth opportunities, and cross-time-zone flexibility.

I am a Computer Science graduate with over five years of remote experience in data annotation, computer vision, and AI projects, collaborating with global teams to build and validate datasets for machine learning and deep learning systems. I specialize in image and video annotation, object detection, semantic segmentation, and data quality assurance using tools like CVAT, Labelbox, Supervisely, LabelImg, and VIA.

I have contributed to self-driving car datasets, retail shelf detection, facial landmarking, and surveillance scene segmentation while training and supervising junior annotators and participating in model validation workflows. I am highly organized, self-driven, adaptable to remote work across time zones, and committed to maintaining annotation accuracy and consistent documentation.
