Freelancer Overview

I am a results-driven Project Specialist with hands-on experience in AI training data workflows, including data annotation, transcription, translation, and evaluation across text, audio, and video modalities. I have worked with global platforms like OneForma and Appen, where I contributed to large-scale projects involving LLM evaluation, search engine relevance assessments, sentiment analysis, and linguistic annotation in both English and Hindi. My core strengths lie in multilingual capabilities, attention to detail, and familiarity with advanced tools such as Labelbox, VOTT, and Prodigy. I possess a solid academic background in Computer Science (M.Sc.) and strong technical skills in Python, NLP, and ML concepts, which empower me to contribute meaningfully to AI development and data-centric projects. With over 15 successful online projects delivered, I bring both technical expertise and project management acumen to every task.
