As an AI Systems Training Engineer, I design and refine training data and workflows that improve the performance of AI systems, particularly large language models (LLMs) in coding and software development tasks. My work involves generating, evaluating, and debugging AI-produced outputs, as well as creating structured datasets such as step-by-step reasoning, tool-use trajectories, and real-world development scenarios. Using tools like Claude and Cursor, I simulate practical engineering workflows, identify model weaknesses, and produce high-quality examples that enhance accuracy, reasoning, and usability.
