    Hi, I am Simon!

    I'm a fintech and payment system architect with leadership experience building and operating sophisticated payment infrastructures at world-class tech companies—Mews, Uber, Miro, and Atlassian.

    In 2025, I launched Cereja so I can help more companies optimize their payment ecosystems. My background uniquely positions me to bridge technical expertise with strategic vision, connecting product, engineering, finance, and operations teams to solve complex payment challenges.

    I specialize in helping organizations overcome payment inefficiencies, tackle integration hurdles, and capitalize on strategic growth opportunities through improved payment infrastructure.

    Experience

    At a global hospitality technology platform, I designed and implemented embedded payment and fintech infrastructure for a hyper-growth business, managing billions in payment volume across 85 countries.

    Earlier in my career, I led payment partnerships at Uber, implementing numerous onshoring initiatives and cost-saving measures that saved millions annually while handling over $100B in transactions across regulated and unregulated markets. I've also helped design and build recurring billing and payment systems at Miro and Atlassian during their critical hyper-growth stages.
