Freelancer Overview

Most annotators label data. I understand what happens to it after. My background as a Product Manager at AI-first companies means I've watched how training data quality directly determines product outcomes, which gives me an unusually sharp sense of what "good annotation" actually requires in practice. I hold a PGD in Advanced Computer Science (University of Sheffield) and a B.Tech in CS, and I've applied that foundation to hands-on annotation work: structuring AI evaluation rubrics used to assess 18,500+ submissions across enterprise-scale pipelines for ISRO and Accenture. My focus areas are text classification, LLM evaluation, RLHF preference labeling, and prompt-response quality scoring. I'm available 20 hours per week, detail-oriented by training, and motivated to build a strong annotation track record on OpenTrain. If you need someone who understands your product goals, not just your labeling guidelines, let's work together.

AI Evaluation Data Structuring - Hackathon Submission Assessment

TextClassification
Worked on converting subjective enterprise evaluation criteria into structured, domain-specific scoring parameters for an AI-assisted assessment system. For each domain, health, blockchain, fintech, sustainability, defined explicit rubrics that broke down vague judging criteria (e.g. "innovation", "feasibility") into granular, scoreable attributes. These structured parameters were used to train and guide the RAG-powered evaluation pipeline to assess 18,500+ hackathon submissions consistently across multiple rounds. The work involved close collaboration with domain experts and enterprise clients (ISRO, Accenture) to ensure the structured criteria accurately reflected real-world evaluation standards.
