I build systems across fintech, infrastructure, and real-world businesses.
About
I've spent 5+ years building in fintech and SaaS. I've worked across North America and Southeast Asia, building platform payments at Xendit, growth and payments products at Paystone, and integrations at Employment Hero.
Currently, I'm building Meimei Matcha — a beverage and distribution business generating ~$230K in annual revenue. I apply the same product thinking across supply chain, operations, and go-to-market, where execution and outcomes matter just as much as strategy.
I'm drawn to building things that operate in the real world — where outcomes are tangible and systems are tested by use, not just design.
Selected Work
Problem
Platforms and marketplaces needed flexible payment flows — multi-party payments, multiple methods, routing — but systems were rigid and required manual work.
Solution
Built APIs and infrastructure for dynamic payment routing, split payments, and onboarding/KYC flows. Designed modular architecture for scalability.
Impact
Problem
Merchants used fragmented tools for payments, marketing, and loyalty — limiting growth and efficiency.
Solution
Built Atom, a unified platform combining payments, marketing, and loyalty. Introduced AI-powered SMS campaign generation.
Impact
What I'm Building
A fast-growing beverage and distribution business generating ~$230K ARR. Operator mindset, real-world execution.
