Message

At Employment Hero, I built HeroClear with the team, an event-driven clearing service for Payday Super that has processed $1B+ in payments. I owned payment flow design, fault-tolerant error handling, and idempotent retries, and collaborated on two-way ledger persistence.

I also engineered features for Swag Spend Account and Earned Wage Access, supporting expansion into Australian and UK markets, and integrated KYB verification for the Canadian launch. Earlier, I developed features at East Agile Vietnam and YOOT Technology & Training JSC; my projects include an interactive 3D acupuncture system and Cong Pha Bazooka, a quiz platform I built and continue to maintain.
