What I'm looking for

I’m seeking a collaborative role where I can lead product design and front-end delivery, focus on accessibility and measurable impact, and work with cross-functional teams to scale design systems and sustainable digital solutions.

I’m a Product Designer and Front-end developer with over six years of experience blending UX/UI, web development and service design to build user-centered, business-aligned digital products. My background in interior design and programming gives me a strong visual sensibility and technical fluency that I apply across projects.

At Llinormatics I led design for Digital Product Passports and a Battery Passport POC showcased at Davos, coordinating with EU officials and blockchain providers to ensure regulatory alignment and stakeholder buy-in. I create research-backed artifacts—user flows, journey maps, service blueprints—and design systems that accelerate development.

I’ve shipped dashboards, data visualizations, and web platforms while improving developer workflows through coded prototypes and reusable UI components. I value accessibility, measurable outcomes (CSAT/NPS improvements), and collaborative, scalable design processes.
