Designed and built proof-of-concept for CFD simulation workflow orchestration using Prefect, with YAML-based schema definition and Python workflow creation. Architected solution inspired by industry tools like Pipedream, Windmill, Stripe Workflows, and Zuora Workflows.

Architected and developed updates to the billing system (Python/Go) to support a new unlimited subscription model, enabling flexible pricing strategies and improved customer value.

Specialized in designing sophisticated payment architectures, integrating a diverse array of payment methods to streamline and enhance our financial operations. Prototyped solutions in Python and Java to ensure their effectiveness.

After leading the implementation for Apple Pay and Google Pay using the Adyen API and front-end components, as well as incorporating SEPA debit, and realizing that Zoom was not able to release new payment methods quickly enough, I designed a payment orchestration architecture which allowed Zoom to release Japanese bank transfers (Furikomi), Sofort, iDEAL, Klarna, and ACH quickly (66% faster).

This architecture interfaced seamlessly with Zuora for billing, and integrated with Stripe and Adyen for diverse payment processing. This multifaceted approach not only broadened Zoom's payment capabilities but also significantly improved the efficiency and reliability of financial transactions, catering to a global customer base and enhancing user experience.
