Head of Technology
HyperCash
Led the creation of HyperCash's technological foundation, which previously had no proprietary systems. I built pixel tracking, the KYC flow with external integrations, payment gateway integration, and the system for info-product creators, with customized creation and checkout and a foundation prepared for AI. I worked with the PO on roadmap management, OKR definition, product vision, and discovery tracking. I also managed production support, assessing incident impact and priority, leading crisis response plans, and ensuring clear communication with all stakeholders.
