Freelancer Overview

I am an experienced data annotator with a background in evaluating and refining Large Language Models (LLMs) to improve model accuracy, reasoning, and safety. My work includes authoring complex, multi-turn prompts to rigorously test model boundaries, performing detailed fact verification to eliminate hallucinations, and conducting high-volume data labeling tasks focused on intent, linguistic nuance, and safety violations. With a keen eye for detail and strong analytical skills developed through my architectural and research experience, I excel at accurately tagging datasets and providing precise feedback for supervised machine learning. I am proficient in tools such as Revit, AutoCAD, and various design platforms, and I thrive in collaborative, multidisciplinary environments where quality and innovation are paramount.

Projects involving a mix of fact-checking, prompt writing and response evaluation, rubrics writing, checking sensitive responses against safety guidelines. Tasks varied from comparison tasks, rating two responses against a set of criteria (truthfulness, tone, formatting); Prompt and response engineering, writing prompts related to a given topic, evaluating 2 responses, writing rubrics to generate a perfect response and writing the ideal response; Creative writing and editing, drafting ideal responses and editing model responses, Fact verification, checking that models are not hallucinating.
