Key Skills

Freelancer Overview

I bring over six years of experience in algorithm engineering and data annotation, specializing in the creation of high-quality, rigorously tested datasets and benchmarks for AI and code LLM evaluation. My background in competitive programming and problem design allows me to craft precise test cases, design robust validation frameworks, and grade problem difficulty with scientific rigor. I am proficient in C#, Python, and C++, and have hands-on experience with modern development tools such as Git, CI/CD, Docker, and SQL databases. My work includes developing libraries of algorithmic problems, building automated validators, and designing adversarial test suites to expose edge cases and ensure data integrity. I am skilled at technical writing in both English and Chinese, and have contributed to open-source online judge systems and authored technical tutorials, making me well-equipped to support data labeling and AI training initiatives in fast-paced, innovative environments.
