Labeling Experience

Code Annotation Specialist

Data Annotation Tech

I performed code correctness reviews and annotation for programming-related datasets in language model pipelines. Responsibilities included evaluating code solutions, flagging logical or factual errors, and annotating for training AI coding assistants. I documented results to meet engineering and data quality benchmarks. • Reviewed computer code for correctness and clarity. • Worked on math reasoning verification projects. • Engaged in NLP and coding annotation using DataAnnotation.tech. • Supported LLM training for code assistance products.

AI Prompt Engineer & Data Trainer

OtherTextPrompt Response Writing SFT

As an AI Prompt Engineer & Data Trainer, I designed and curated prompt-response pairs and datasets for fine-tuning LLMs in various domains. My work included building a template library and evaluating model outputs for factuality, tone, instruction-following, and safety. I ensured deliverables met stringent quality and inter-annotator agreement metrics. • Built a 200+ prompt template library for EdTech AI essay feedback. • Provided structured model output feedback to engineering teams. • Delivered annotated datasets with documented quality standards. • Operated in journalism, law, education, support, and creative writing domains.

Senior Data Labeller & RLHF Specialist

Scale AITextRLHF

As a Senior Data Labeller & RLHF Specialist, I contributed over 3,000 human preference comparisons for LLM training including GPT-4, Claude, and Gemini. I performed comparative response ranking, instruction-following evaluation, and factuality/safety assessments through reinforcement learning from human feedback workflows. I maintained exceptionally high annotator quality scores, flagged hallucinations, and supported engineering teams with rationale notes. • Annotated conversational datasets for tone, intent, sentiment, toxicity, and policy alignment. • Completed tasks like multi-turn dialogue evaluation, summarization quality rating, code correctness review, and math reasoning checks. • Trained junior annotators, improving team throughput and quality. • Worked across Scale AI, Appen, Remotasks, Lionbridge, and DataAnnotation.tech platforms.

Content Moderator & Trust & Safety Reviewer

OtherTextClassification

In my role as Content Moderator & Trust & Safety Reviewer, I reviewed, labeled, and actioned thousands of pieces of text, image, and video content daily. I applied multi-class content labeling to enforce policy and flagged edge cases and adversarial content as needed. My detailed moderation logs informed weekly analytics and content policy revisions. • Applied hate speech, misinformation, NSFW, violence, spam, and IP violation labels. • Escalated edge and policy-grey cases to trust-and-safety teams. • Maintained high accuracy and zero-tolerance for harmful content. • Contributed to policy audits and reduction of harmful content incidents.
