Stephanie Siaw is a veteran engineering manager and full-stack software engineer with 12 years of experience building scalable consumer platforms and leading teams of 20+ engineers at unicorn startups and Fortune 500 firms. As Co-Founder of PO2 Studio she combines product strategy, design systems and hands-on development—spanning React/TypeScript frontends, Ruby backends and modern no-code stacks—to help businesses multiply growth. At Deliveroo she drove grocery and pricing initiatives that materially increased user growth and retention across multiple markets while also shaping org-wide engineering management practices. She’s equally comfortable shipping greenfield products, running user research, and coaching healthy, high-performing teams that dedicate time for experimentation. Based in Hong Kong, Stephanie brings international experience from consultative roles at Thoughtworks to advisory work for early-stage startups, blending technical depth with product and people leadership. An uncommon strength is her track record of institutional improvements—like EM levels, on-call onboarding and gamedays—that scale developer capability beyond individual projects.
