Freelancer Overview

I am an experienced full stack web developer with over 5 years of hands-on experience, specializing in frontend technologies and AI model training data. My recent work as a Frontend Web Developer Expert involved designing high-quality code prompts, test cases, and solution reviews to train and evaluate AI models, focusing on improving coding accuracy, reasoning, and best practices. I have a strong background in analyzing and correcting AI-generated outputs, ensuring logical consistency, maintainability, and real-world applicability. My skill set includes JavaScript, React, Next.js, Node.js, RESTful APIs, and modern development tools like Git, Docker, and Visual Studio Code. I am adept at collaborating in cross-functional teams, following structured workflows, and delivering precise, high-quality training data for AI systems in software development and web application domains. My technical writing experience further enables me to create clear documentation and annotation guidelines, making me passionate about contributing to reliable and effective AI training data processes.

Worked as a Data Annotator and AI Model Evaluator on a full-stack web development benchmarking project (0–1 application builds). Designed complex, realistic prompts simulating real-world developer workflows (e.g., React, Node.js, authentication, database integration) to test AI coding agents. Evaluated model outputs using structured rubrics across dimensions such as planning, instruction-following, code quality, debugging ability, tool usage, and context awareness. Conducted side-by-side model comparisons, tagged error types (e.g., context ignored, incomplete debugging, security risks), and provided detailed scoring rationales to ensure consistent and high-quality evaluation.
