Kvika payment processing platform

Straumur
Problem

Financial products demand trust, clarity, and reliability. Merchant flows span onboarding, service portals, and operational tooling — each with different user mental models but one brand system.

Approach

I treated each flow as part of a coherent product language: strong hierarchy, restrained motion, and frontend patterns that made complex payment concepts scannable for non-technical merchants.

Results

Delivered production frontend work for a regulated payment platform used at national scale — balancing compliance-minded UX with modern React architecture.
