Josh Choo

I’m a software engineer in fintech, focused on distributed systems for financial products, payment workflows, and high-volume transaction processing.

Over the past several years, I’ve worked on card transaction processing at Airwallex, realtime reconciliation at TikTok, payments and monetization at Indeed, and financial projection and trading systems at StashAway.

I take a pragmatic, high-ownership approach to building production systems that are correct, reliable, maintainable, and practical to operate.
