Labeling Experience

Image Annotation & Data Labeling Specialist

CVATImageBounding Box

As an Image Annotation & Data Labeling Specialist, I performed image annotation for classification and object detection tasks. I used CVAT and LabelImg to draw bounding boxes and assign labels on complex image datasets. My annotations supported dataset preparation and quality control for computer vision training. • Annotated images for multiple vision tasks including object detection and classification. • Utilized CVAT and LabelImg platforms for efficient image data processing. • Supported quality assurance and dataset readiness for model building. • Ensured labeling best practices and standardization in computer vision workflows.

Speech & Voice Data Annotator

OtherAudioTranscription

As a Speech & Voice Data Annotator, I transcribed and labeled large volumes of audio data to improve automatic speech recognition systems. I annotated audio clips to identify user intent and performed linguistic validation for text-to-speech models. My work ensured accurate recognition of speech and natural prosody in synthesized outputs. • Transcribed and labeled audio files for ASR training. • Annotated intent and entity in diverse audio scenarios. • Conducted validation to enhance TTS model quality. • Focused on enhancing speech recognition across varied accents.

AI Training Specialist (Text & NLP)

OtherTextRLHF

As an AI Training Specialist, I evaluated and ranked AI-generated text responses based on Helpfulness, Honesty, and Harmlessness (HHH) principles. I performed fact-checking and grounding tasks by cross-referencing model outputs against trusted sources to reduce hallucinations and improve factual accuracy. I authored 'Golden Sets' of ground-truth responses to fine-tune large language model (LLM) performance for a variety of prompts. • Conducted assessments of AI responses for helpfulness and safety. • Verified claims made in model outputs for factual grounding. • Created high-quality reference responses for complex prompts. • Specialized in Reinforcement Learning from Human Feedback (RLHF) for natural language tasks.
