👋 Hi, I’m Tokuma Sime

A Product & UI/UX Designer and Top Rated Freelancer on Upwork, passionate about building intuitive, user-focused digital experiences. I specialize in mobile and web design, prototyping, wireframing, and user research using tools like Figma and Adobe XD, delivering clean, functional, and impactful solutions.

I’ve designed 100+ web applications and 20+ mobile apps across industries such as SaaS, e-learning, dashboards, and e-commerce, collaborating closely with developers to ensure smooth implementation. As Lead Designer at Helder Technologies Solution, I guided a team of designers, mentored juniors, and delivered high-standard projects for both local and international clients.

Alongside my digital design career, I hold a B.Sc. in Leather Product Engineering (Gold Medalist, Bahir Dar University), which strengthens my ability to merge creativity with technical precision. This unique mix allows me to solve problems with fresh perspectives while delivering designs that balance usability, beauty, and business goals.
