Product Designer Gubenko Portfolio

Hey!
My name is Dmitrii Gubenko
I'm Product Designer

Fintech • Payments • B2B / B2C • Design Systems • Leadership • Mentorship • Hiring

I’m a product designer with 8+ years of experience in fintech, crypto, and complex digital products.

I enjoy working with complex interfaces — dashboards, CRM systems, and back-office tools — and turning them into clear, efficient products that people can actually use.
I’m hands-on in my work: I design key user flows, build systems, collaborate closely with developers, and make sure solutions get shipped to production — not left in mockups.

Selected results:

Increased conversion rates and task success by 10–12%
Reduced user churn and error rates by 15–20%
Accelerated development speed by 10–15% through design systems
Helped teams move faster and deliver more consistently

Core skills:

Complex interfaces: dashboards, CRM, back-office systems
Design systems (components, tokens, libraries)
Figma — advanced level
Product UX and funnel optimization
Data-driven design and hypothesis validation
Cross-functional collaboration with engineering
Mentoring designers and driving work to completion
