( 01 ) — In short
I took an app from about 55% to 95%+ on Lighthouse. I built a FIFA World Cup Qatar 2022 ticket-booking experience that supported about $20,000 in revenue per match event. I advocated Next.js as the foundation of a multi-store SaaS platform. I care about the decisions behind the pixels.
