I'm a Machine Learning Software Engineer at Amazon, specialising in Forward Deployed AI engineering — partnering directly with stakeholders to turn manual, high-friction workflows into production AI systems. I'm currently on the AI Ops Integration team, automating supply chain processes with agentic AI and computer vision, while driving R&D (research and development) at the intersection of both.
