Data Tutor
In my last role, I worked on a data annotation project to help train AI for fully autonomous drones. The goal was to make drones smart enough to fly and make decisions on their own in real world situations which involved delivery of packages for clients who purchased them online. My main tasks were labeling images taken from drone cameras. I drew bounding boxes around objects (like people, vehicles, trees, buildings), did pixel-level segmentation to separate things like sky, ground, and obstacles, and added extra information such as distance or whether something was moving. We used tools like segments.ai and labelbox. The project was quite large. My team labeled over 700,000 images in about 35 months. For quality, we followed strict rules. Every image got checked by at least two people, we kept inter annotator agreement above 95%, and the final error rate stayed under 2%. We also had regular reviews, automated checks, and feedback sessions to keep everything consistent and accurate.
