What I'm looking for

I am seeking product design roles—remote or relocating—where I can scale design systems, improve usability through research-led work, mentor teams, and deliver measurable product and business impact.

I am a Product Designer specializing in scalable UX design, design systems, and product optimization for fintech and SaaS platforms serving international markets. I bring end-to-end product design experience including research, prototyping, usability testing, and cross-functional collaboration.

At Luby Software I led end-to-end UX/UI across multiple projects, created a unified multi-product Design System, and partnered with sales and marketing to develop case studies using product data. My work contributed to measurable savings and improved UI scalability and transaction clarity.

As a freelance Product Designer and earlier as a Graphic Designer and Art Director, I redesigned core UIs, built scalable style guides, conducted user research, and produced brand systems and motion assets for clients and high-profile media events. I mentor designers on design systems, UX processes, and workflow optimization.

I seek opportunities where I can apply structured UI systems, drive measurable product improvements, and collaborate with cross-functional teams to scale design solutions for international users.
