About

Engineering leader and former hedge fund founder with 10+ years of experience building and scaling mission-critical systems across education, healthcare, enterprise, AI, and finance. Former Lead Software Engineer at Khan Academy and part of the White House “tech surge” that rescued HealthCare.gov. Most recently founded and ran a quantitative hedge fund dedicated to funding regenerative impact. Skilled at defining technical vision, building and mentoring high-performing teams, and aligning engineering strategy with ambitious social missions. Deep full-stack background (frontend, backend, data, ML, DevOps) with particular strength in product UX and data platforms. I am currently seeking a position where I can leverage my skills to address the root causes of the polycrisis to create a more just, harmonious world that respects the sanctity of all life.
