Hans User

I’m a BSIT student specializing in AI-assisted development and data annotation, with a proven track record as an Independent Contractor at Outlier. I execute high-quality data labeling and quality assurance to train Large Language Models (LLMs), applying rigorous evaluation standards to identify and correct inconsistencies in generated data. I’m especially driven by prompt engineering—crafting precise prompts in ChatGPT and Gemini to generate, test, and refine accurate outputs with strong ethical focus.

Beyond labeling, I bring technical depth for end-to-end delivery: strong technical literacy in HTML, CSS, React.js, and Python, plus database experience with Firebase, Firestore, and MySQL. I’ve also taken on full-stack work across projects and contribute with system thinking as a System Architect and Project Manager, supported by tools like GitHub Copilot, Cursor IDE, and Windsurf IDE. My goal is to build reliable data and software systems that perform well in real-world use.
