Emmanuel Adebisi

I’m a Staff Software Engineer who’s spent the last several years designing high-performance backend systems that directly move product metrics—whether that’s improving Prime benefit recommendations for 200M+ members at Amazon or scaling AI-driven health experiences at Oscar Health. At Amazon, I led backend and infrastructure work that improved real-time Prime recommendations by 15%, reduced recommendation latency by 25% during high-traffic events, and boosted Prime Day offer-driven sales by 20%.

I also build systems end-to-end: migrating legacy services to AWS to cut infrastructure costs by 30%, strengthening analytics frameworks to improve conversion by 12%, and integrating key mobile experiences. Earlier at Oscar Health, I developed core web and backend technologies, powered an AI claims assistant automating 48,000 investigations annually, and helped deliver virtual care that cut wait times by 90%—while mentoring junior engineers and driving clean, reliable engineering practices.
