Freelancer Overview

I am an experienced UX/UI and product design specialist with a strong background in developing high-quality training data, annotation guidelines, and scalable documentation for AI and machine learning applications. My work spans logistics, agriculture, and edtech, where I have led projects focused on metadata structuring, content QA, and creating WCAG-compliant, human- and machine-readable documentation. I have collaborated closely with engineering and editorial teams to optimize data labeling workflows, implement version control, and ensure the accuracy and consistency of training datasets for intelligent interfaces. My technical skills include Figma, React, and modern web technologies, and I am adept at designing accessible, component-driven UI systems that support both user experience and AI readiness. Currently pursuing a master’s in Computer Science with an AI specialization, I am passionate about building robust data pipelines and documentation that empower both human annotators and automated systems.
