What I'm looking for

I’m looking for a product team where I can own end-to-end UX, build and maintain design systems, partner closely with engineering and marketing, and use AI to improve design workflows and user outcomes.

I’m a multidisciplinary product designer with 8+ years of experience across UI/UX, branding, and digital strategy. I work end-to-end—from discovery and information architecture to final delivery—building intuitive, conversion-oriented digital experiences.

I’ve thrived in both agency and startup environments, collaborating closely with product, development, SEO, and marketing teams. I’m especially strong in stakeholder communication: presenting and defending design decisions while structuring my product rationale clearly.

In my current role, I lead end-to-end management of digital projects, from briefing and strategic planning to high-fidelity prototypes, design specifications, and final delivery. I maintain components, style guides, and visual documentation standards, and I design websites, navigation flows, and interfaces grounded in UX and information architecture.

Across freelance and client work, I design complete website structures combining UI/UX, information architecture, and content strategy for B2B and B2C audiences. I also use research and performance insights—conducting usability testing, heatmap analysis, and user behavior research—to guide UX and content decisions, and I’ve supported paid traffic strategy (Google Ads) and SEO planning. I have a strong interest in AI applied to design processes and emerging technologies.
