Product Owner, Advapay
Evgeniy Zelenskiy is Product Owner at Advapay, where he works on the Macrobank core banking platform - the system of record behind accounts, payments, ledger operations, reporting, and regulated fintech workflows. His work focuses on turning complex banking and payment capabilities into configurable modules that fintech teams can launch and operate without building the full stack from scratch.
Across Advapay's licensing and platform projects, Evgeniy has seen how product decisions affect implementation timelines, operational control, and audit readiness. He works with requirements that sit between business model, compliance expectations, and software delivery: account structures, payment flows, cards, integrations, user roles, reporting, and the control points regulated financial businesses need before go-live.
Evgeniy writes about core banking software, platform architecture, product configuration, and the practical infrastructure choices fintech operators face when choosing between custom builds, vendor platforms, and modular core banking systems.
