What I’m Known For

These are the areas I consistently focus on when designing digital products.

  • Clear & Scalable Product Flows

  • I design complex product flows, such as onboarding, investment, and B2B integrations, with clarity, scalability, and clear logic for both users and teams.

  • Designing for B2C & B2B Contexts

  • Experienced in designing products across B2C and B2B environments, balancing user needs, business rules, and technical constraints, especially in partner integrations and white-label systems.

  • Strong UI with Brand Adaptation

  • With a background in graphic design, I create clean, consistent interfaces and adapt UI effectively across different brand guidelines and partner ecosystems.

  • Product Thinking & Collaboration

  • I work closely with PMs, engineers, and stakeholders to translate business requirements into practical design solutions, ensuring alignment throughout the product lifecycle.

Notes

from My Work

Most usability issues come from unclear flows, not visuals

In many cases, problems aren’t caused by visuals but by confusing logic, missing steps, or unclear user paths—especially in complex financial features.

Good UI doesn’t fix a broken product logic

Polished interfaces can’t compensate for unclear requirements or flawed business rules. Fixing the logic early saves much more time later.

Designing for B2B often means designing for constraints

Partner products often come with technical, branding, and business limitations. The challenge is finding clarity within those constraints.

Consistency matters more than novelty

Users feel more confident when patterns stay familiar, especially in finance. New ideas only work when they don’t break trust.
