Freelancer Overview

I am a frontend engineer with 4+ years of programming experience across React, Next.js, JavaScript, TypeScript, APIs, JSON, and software workflows. This makes me well suited for AI training tasks involving code review, technical explanation, prompt evaluation, and response quality rating. I am also comfortable with broader AI training work, including text review, image classification, audio evaluation, transcription review, video assessment, data labeling, and rubric-based annotation. My strengths are accuracy, attention to detail, clear English communication, and the ability to follow guidelines consistently across different data types.

AI Response Evaluation for Technical and Customer Support Tasks

TextEvaluation Rating
I reviewed AI-generated answers to make sure they were clear, accurate, natural, and relevant to the task. This included customer support replies, technical explanations, JSON and configuration questions, troubleshooting steps, and short spoken-response answers. My focus was on checking whether the answer actually solved the user’s problem, followed the instructions, avoided guessing, and used simple English that would be easy for a real person to understand

React / JavaScript Code Review and AI Response Evaluation

Computer Code ProgrammingComputer Programming Coding
I reviewed AI-generated coding responses and frontend code examples for correctness, clarity, and practical usability. The work involved checking React, JavaScript, TypeScript, API handling, JSON structure, debugging explanations, and whether the answers followed the user’s instructions. I assessed code quality, identified bugs, corrected logic errors, improved explanations, and rated responses based on accuracy, completeness, and usefulness.
