Andrii Stetsenko is Chief Software Architect at Wyllo (formerly NoFraud), where he owns the end-to-end technology architecture across Services, Data, and AI — shaping the technical direction of the entire organization. Previously, he was the Founding CTO and product co-creator of Yofi.ai, building the platform, team, and product from zero. Under his leadership, Yofi.ai was recognized as one of the Top 100 Leading Startups of 2023 and later acquired by NoFraud.

Andrii spent over a decade architecting enterprise-scale systems at Adidas (Director Software Architecture), Gucci (Principal Software Architect), Alibaba (Senior Software Architect), and Nike (Big Data / Data Science Tech Leader), where he built secure, high-performing data and AI platforms supporting billions of events. He achieved 80% reductions in licensing costs at Adidas, 70% cloud savings, and 12–18% sales growth through AI-driven commerce and generative AI implementations.

He is a decorated hacker — winner of the Shenzhen International Hackathon (1st Place), UBS Internal Hackathon (Hong Kong), and EPAM China International Hackathon — and a nominee for the Adidas Architecture of the Year Award. His current focus is on agentic AI architecture, cross-timezone enterprise automation, and security-by-design for autonomous agent networks.
