Are you looking for a data annotator who delivers clean, accurate datasets on time, every time? I've completed 10+ projects on Upwork with a 100% Job Success Score and five star reviews across the board. Clients keep coming back because I get the details right and communicate clearly throughout. I mostly work on image and video annotation including bounding boxes, polygons, segmentation, keypoints, and object detection. I've annotated everything from marine vessels and LiDAR point clouds to football images and product datasets. I also take on text and NLP tasks like LLM evaluation, RLHF, text classification, and fact checking when needed. Tools I use daily: CVAT, Labelbox, Roboflow, SuperAnnotate, BasicAI, LabelImg. I can deliver in YOLO, Pascal VOC, COCO JSON, or whatever format fits your pipeline. And if you have a custom tool, I pick things up fast. Beyond annotation, I also handle data entry, spreadsheet work, B2B lead generation, list building, and general VA tasks. I've worked with LinkedIn Sales Navigator, Apollo, Excel, Google Sheets, and various CRMs. My process is simple. I start with a small sample batch to make sure I understand your guidelines before scaling up. I'm available 40+ hours a week, I respond quickly, and I don't miss deadlines. If any of this sounds like what you need, send me a message and let's talk about your project.
