Machine Learning Engineer

Technical lead across platform, mobile, and MLOps. Proposed and built the company’s Swift SDK end to end, unprompted, from architecture through documentation and rollout. Led the second version of Bel Esprit, the platform’s agent-orchestration system, holding the orchestration logic, agent-to-agent communication, and code generation constraints as one coherent design. Also compressed a distributed, multi-container platform into a standalone Mac application with no cloud dependency.
