Raymond I.

AI Data Annotation Specialist helping AI and ML teams get accurate, guideline-compliant training data: image and video annotation, captioning, search relevance evaluation, and QA, delivered consistently and on schedule. With about 3 years of hands-on experience in AI data work and 600+ hours logged on Upwork, I am used to long-running projects with detailed guidelines, quality checks and tight turnaround. WHAT I DO • Image & video annotation: bounding boxes, segmentation and classification for computer vision models • Image & video captioning: clear, consistent descriptions that follow your style guide • Search relevance & search engine evaluation: rating results against query intent and guidelines • Text annotation & NLP labeling: sentiment analysis, content moderation and classification • Audio & video transcription • Data quality review (QA): checking, cleaning and structuring datasets • Tools: Labelbox, Google Sheets HOW I WORK ✔ I read the guidelines closely and apply them the same way across every item ✔ I flag edge cases and unclear instructions early instead of guessing ✔ I keep data confidential and follow security requirements ✔ I communicate clearly and report progress regularly If you are building a computer vision model, improving search quality or preparing a dataset for training, send me a message with a short description of your project, your guidelines and your quality targets. I am happy to complete a small paid pilot task so you can check my accuracy before we scale up.
