Freelancer Overview

I bring 7 years of hands-on experience in data labeling and AI training data across a wide range of platforms, including Labelbox, Scale AI, Appen, Lionbridge, DataLoop, CVAT, Aether, and others. Over the course of my career, I have worked on diverse data types — text annotation, image segmentation, audio transcription, video tagging, and sentiment classification — supporting the development of machine learning and NLP models across industries including autonomous vehicles, healthcare, and conversational AI. My work has consistently met strict quality benchmarks, with a strong understanding of annotation guidelines, inter-annotator agreement, and iterative feedback workflows that ensure high-quality training datasets.

Labeling Experience

Senior Technical Writer

Computer Code ProgrammingRLHF

Own the end-to-end documentation lifecycle for a Kubernetes-native SaaS platform serving 400 + enterprise customers, covering conceptual overviews, step-by-step tutorials, and REST/GraphQL API references. • Introduced a docs-as-code pipeline (GitHub Actions + MDX + Vale linter) that reduced broken-link incidents by 60 % and cut review cycle time from 5 days to 1.5 days. • Partnered with ML engineering to produce training, inference, and fine-tuning guides for the company's LLM integration layer, driving a 35 % drop in related support tickets within 90 days of publication. • Mentored two junior writers and led quarterly style-guide reviews to maintain consistency across 1,200 + documentation pages. • Implemented documentation analytics (Mixpanel + custom dashboards) to identify high-bounce pages and prioritise rewrites, improving average time-on-page by 28 %.
