What I'm looking for

I seek a collaborative product-design role where I can lead end-to-end UX, build scalable design systems, work cross-functionally, and create accessible, measurable product improvements.

I am a creative, user-driven Product Designer and Digital Illustrator with over 4 years of experience crafting intuitive, impactful digital solutions across Web3, Healthcare, Fintech, and SaaS. I lead end-to-end design processes, conduct user research and usability testing, and build design systems that scale while improving customer satisfaction and engagement.

My work has produced measurable results — from boosting conversions and retention to increasing CSAT and engagement — through close collaboration with developers, PMs, and stakeholders. I am passionate about accessibility, emerging technologies, and optimizing workflows to deliver polished, effective product experiences.
