Mathieu is an AI Evaluation Engineer at Handshake AI’s Project Dynamo\. He authors adversarial benchmark tasks used to measure frontier LLM coding\-agent capability, while completing his Computer Science studies in Intelligent Systems at UC Irvine\. ### What does Mathieu do at Handshake? Mathieu builds adversarial benchmark tasks in Terminal\-Bench 2/Harbor format\. For each task, he develops the Docker environment, synthetic\-data generator, reference solution, and automated verifier end to end in Python\. ### What did Mathieu accomplish in LLM\-agent evaluation?
