Freelancer Overview

I have several years of experience as a software engineer, with a strong focus on backend development, API integration, distributed systems, and automated trading platforms. In recent years, I have also worked extensively with AI technologies, including large language models (LLMs), prompt engineering, model deployment, and AI-assisted development workflows. My work often involves analyzing large volumes of structured and unstructured data, validating outputs, identifying inconsistencies, and improving system reliability through testing and optimization. Although I have not held a dedicated data labeling role, I am familiar with the principles of data annotation, quality assurance, and evaluation. Through software development and AI-related projects, I have developed strong attention to detail, the ability to follow complex guidelines, and experience assessing the accuracy and consistency of model-generated outputs. These skills enable me to contribute effectively to AI training, data annotation, and model evaluation tasks.

While I have not worked in a dedicated data labeling position, I do have relevant experience that aligns closely with AI training and evaluation work. As a software engineer, I regularly analyze large datasets, validate data quality, test system outputs, identify inconsistencies, and follow detailed technical specifications. I have also worked extensively with AI models, including prompt engineering, model evaluation, and assessing the accuracy and reliability of AI-generated responses. Therefore, I would describe my background as having relevant AI and data quality experience rather than formal data labeling experience.
