PRODUCT DESIGNER
BASED IN CHICAGO, USA

VIKTORIIA CHISTIAKOVA

Senior Product Designer with 7+ years in EdTech and FinTech. From gamified learning for children to enterprise B2B to large-scale banking. I build conversion-driven experiences through activation mechanics, funnel optimization, and systematic testing.

Voice-First Card Blocking
for 100M+ Users

Challenge: When cards were lost, stolen, or stuck in ATMs, panicked users called support and waited on hold. They struggled to locate the blocking feature in the app, while the voice assistant only redirected them to handle it manually.

Solution: Integrated card blocking directly into voice assistant, eliminating the need to switch to the app and removing 5 unnecessary steps. Users can now block their card instantly by voice alone.

Gamified Learning
for Elementary Students

Challenge: Elementary segment (ages 5-10) had low conversion. Traditional formats didn't engage young learners, and parents didn't see enough value to purchase.

Solution: Designed gamified learning with achievement systems and progress visualization. Created reward loops that engaged children while showing parents clear learning outcomes, validated through A/B testing.

B2B Platform for Corporate Holdings

Challenge: Holdings had no platform to manage banking products across their companies – everything tracked manually. Alfa Bank (35M users) aimed to grow corporate clients and 2x products per company, but reliance on personal managers limited growth.

Solution: Built B2B platform where holdings connect products to entire corporate groups, manage everything in one place, and access optimized group tariffs – enabling unified visibility, better pricing, and reduced manager dependency.
