Data Annotation & AI Training Specialist specializing in computer vision, audio, and text evaluation for accurate model outputs.
What I'm looking for
I’m a detail-oriented Data Annotation & AI Training Specialist with hands-on experience across image, video, audio, and text tasks. I focus on precise labeling—image segmentation, region labeling, and OCR—so models learn accurately from high-quality training data.
In video workflows, I annotate frame-by-frame using bounding boxes, polygons/segmentation masks, and multi-object tracking. I keep labels consistent through motion and occlusion using keyframe interpolation, event detection, and temporal region labeling with frame-level accuracy.
I also evaluate AI outputs to improve quality and trust. I perform audio comparison and evaluation, transcription-focused tasks, and rubric-based response ranking (A/B), marking errors such as factual inaccuracies, hallucinations, instruction-following failures, and formatting issues.
Beyond annotation, I bring 7+ years of independent technical work in Web3 research, technical content evaluation and writing, and vulnerability research. This strengthened my fact checking, critical analysis, and structured documentation approach—skills I use to follow detailed, evolving guidelines and deliver reliable results in remote, deadline-driven environments.
