Led end-to-end design for a B2C fintech mobile app serving 500K+ monthly active users, driving a 34% increase in task completion rates through a full redesign of the core payment flow. Research & Strategy: Conducted 40+ user interviews and synthesized findings into actionable journey maps, identifying 12 critical pain points that informed the product roadmap for two quarters. Interaction Design: Translated complex data-heavy workflows into intuitive interfaces; reduced average session time by 28% while improving user-reported task ease scores (SEQ) from 4.2 to 6.1. Design Systems: Built and maintained a scalable component library in Figma with 60+ components and variables, cutting design-to-dev handoff time by ~15 hours per sprint and ensuring 99% visual consistency across iOS, Android, and Web. Collaboration: Partnered with PMs and engineers in Agile sprints, facilitating design critiques and usability tests that prevented an estimated $80K in re-work costs by catching issues pre-development. Visual Design: Directed the brand’s visual evolution, introducing a modernized color system and typography scale that improved brand trust scores by 18% in post-launch surveys.
