Available to hire
I’m Lemuel Castillo, a UX/UI & visual designer with over 14 years of experience blending user-centered product design with strong brand execution across digital and print. I’m especially passionate about turning complex information into clear, intuitive experiences—using end-to-end UX research, wireframing, and high-fidelity prototyping to solve real user friction and support business goals.
Across roles in UX design, e-commerce, and campaign production, I’ve built dashboards, ROI tools, learning experiences, and mobile-first redesigns, while also leading creative production and improving workflow efficiency through better systems and quality control. I thrive collaborating with stakeholders—from CEOs to developers—bringing clarity to requirements, confidence to design decisions, and polished creative output using Figma, Adobe Creative Cloud, and AI-assisted workflows.
