Freelancer Overview

I have strong experience in AI training data and data labeling through my work at Turing, where I contributed to large-scale LLM training and evaluation projects. My work focused on creating, reviewing, and improving high-quality technical datasets across DSA-related tasks, web development data creation, unit testing, data analysis, and coding workflows. I evaluated model outputs, identified failure patterns, improved prompt/response quality, and ensured that the data met strict accuracy, clarity, and usefulness standards. I also worked across different AI tool-based projects, including browser-based tasks, image generation evaluation, code tools, and advanced data analysis workflows. In addition to hands-on labeling and evaluation, I served as a team lead, guiding quality standards, reviewing work, mentoring engineers, and onboarding 100+ contributors. This experience helped me build strong judgment in AI data quality, technical evaluation, guideline interpretation, and scalable team execution.

Software Engineer | ML/DL Engineer (RLHF Expert)

TextRLHF
As an RLHF expert, I contributed directly to improving the quality and reliability of production-scale LLM systems. My work involved analyzing model outputs, identifying edge cases, and applying reinforcement learning from human feedback to enhance model performance. I maintained high-quality evaluation standards across multiple advanced LLM features. • Led evaluation of LLM model outputs, focusing on accuracy and reliability • Enhanced robustness of LLM features such as Advanced Data Analysis and Browser • Mentored and onboarded a team to uphold consistent evaluation standards • Collaborated to refine and align model behavior for real-world use cases
