Freelancer Overview

I specialize in building and curating high-quality datasets for AI and machine learning applications, with hands-on experience as an LLM Trainer where I executed complex multi-step workflows and delivered over 200 error-free demonstrations for frontier AI models. My technical background spans Python, C++, Docker, Git, and Linux, and I am adept at following precise SOPs to ensure data accuracy and reproducibility for machine learning pipelines. I have also developed AI-powered platforms and worked with tools such as Prisma, PostgreSQL, and Next.js, further strengthening my understanding of data annotation, system configurations, and technical documentation. My experience with terminal automation, secure data handling, and real-time data processing enables me to contribute effectively to projects requiring meticulous attention to detail and robust data labeling practices.

Worked as an LLM Trainer on the Computer Use Evals project, contributing to training and evaluation of AI agents performing real-world browser and system tasks. Executed 200+ high-quality demonstrations involving multi-step workflows such as file management, Docker operations, Git workflows, and cross-platform system configurations. Performed response evaluation using structured rubrics including task completion, factual accuracy, and AI performance, ensuring strict adherence to SOPs and justification templates. Identified objective claims, validated outputs, and maintained high-quality standards with zero tolerance for deviations in execution paths, naming conventions, and sequence accuracy. Contributed to improving model reliability by providing precise, reproducible, and well-structured training data aligned with production-level requirements.
