Freelancer Overview

I am a freelance AI data annotator with hands-on experience across multiple annotation domains including video captioning, image annotation, speech audio labeling, and web browsing task recording. I have completed projects on several professional platforms, working with structured, multi-field guidelines that required strict accuracy, objectivity, and consistency across high volumes of tasks. I enjoy picking up new annotation formats quickly and bring the same level of reliability and attention to detail to every project I work on. What sets me apart is the breadth of my experience across different data types and platforms, combined with a Computer Science background that helps me understand the technical context behind AI training data. I am comfortable working independently, adapting to new tools and workflows with minimal onboarding time. I am actively looking to expand into new annotation domains and contribute to impactful AI projects.

Labeling Experience

Video Segment Annotation

VideoText Generation
As a Video Segment Annotator for Atlas Capture, I provided accurate descriptive sentences for task-oriented video segments. Each segment was carefully identified, split, or merged to match required durations while maintaining annotation quality. I focused on annotating steps to reflect goals rather than simple actions. • Generated present participle captions for all segments • Managed segmentation boundaries per project rules • Maintained 8–40 second annotation standards • Enhanced video analysis with goal-based summaries

Web Browsing Task Annotation

TextData Collection
As a Web Browsing Task Annotator for Snorkel AI, I recorded comprehensive web interaction sessions using structured annotation protocols. Each recorded session detailed the atomic actions taken, supported by stepwise screenshots, ensuring traceable interaction data. Final summaries were composed to answer both explicit and implicit task questions, aligning outcomes with annotation guidelines. • Logged granular web browsing actions with Chrome extension tools • Provided structured final documentation addressing all task queries • Maintained consistency by noting session restarts and anomalies • Delivered complete browsing traces for model training datasets

Speech Audio Annotation

AudioClassification
As a Speech Audio Annotator for TransPerfect DataForce, I annotated English speech recordings for various acoustic qualities and vocal characteristics. Labels described audio clarity, speaker style, and intonation, prioritizing diversity and natural human insights over templates. • Evaluated recordings for quality and delivery • Provided unique descriptions in each task • Emphasized pitch, pace, and speaker emphasis in annotations • Avoided repetition and standardized phrasing to boost variety

Video Captioning Annotation

VideoText Generation
As a Video Captioning Annotator for Micro1, I produced detailed, multi-field captions for video datasets. Captions included scene summaries, timestamped events, and nuanced object interactions, supporting advanced AI understanding. All annotations maintained objectivity and followed strict guidelines for causal and numerical reasoning. • Generated multi-field captions covering scene summaries, character descriptions, and camera analysis • Annotated timestamped action sequences and scene cuts with precision • Applied causal reasoning between subjects and objects across all annotations • Maintained strict objectivity and numerical accuracy throughout all tasks

Data Annotation

ImageBounding Box
As a Data Annotator for MoonValley, I labeled product and lifestyle images with bounding boxes and extensive metadata. Each task required product classification, captioning, and visual detailing to support AI models to recognize products on e-commerce platforms. I entered product URLs, brand details, and managed metadata for hundreds of annotated images. • Drew bounding boxes for product localization • Provided short and detailed image captions • Categorized products by type and sub-category • Annotated lifestyle scenes showing products in context
