Freelancer Overview

I am an AI training and operations specialist with over 7 years of experience working on large-scale data annotation, prompt authoring, and evaluation for LLMs and workflow simulation projects. My expertise includes building and grading complex prompt datasets within Non-UI Gym and Cross-Gym environments, focusing on multi-step reasoning, tool orchestration, and structured benchmarking. I have a strong track record in validating AI outputs for accuracy, coherence, and adherence to real-world business workflows, particularly in SaaS, CRM, project management, and event operations domains. I am proficient with tools such as Salesforce, HubSpot, Zendesk, Jira, Asana, and Google Workspace, and I excel at analyzing, annotating, and improving AI training data to ensure high-quality model performance. My background in technical writing and operational optimization enables me to deliver clear, actionable feedback and maintain robust documentation to support both human and automated systems.

Worked as a Subject Matter Expert supporting LLM training and evaluation across structured Non-UI and Cross-Gym environments. Authored and evaluated 700+ prompts simulating real-world business workflows across communication systems, CRM platforms, project management tools, and event management environments. Performed comparative A/B response evaluations using rubric-based scoring frameworks. Assessed outputs for task completion, reasoning depth, tone alignment, hallucination detection, constraint adherence, and tool invocation accuracy. Designed multi-step cross-tool scenarios requiring coordinated reasoning between email systems, calendar scheduling, CRM updates, task management platforms, and document workflows. Identified weak, generic, or logically inconsistent responses and produced improved benchmark outputs aligned with evaluation standards. Maintained structured QA processes and high data integrity standards to support model alignment and reasoning robustness.
