About Me

Portrait of Amadeus Rennalls smiling, wearing a black T-shirt against a pale background

I'm a Lead Product Designer with over six years of experience designing digital products across web and mobile. My work focuses on clear, thoughtful experiences that solve real user problems while supporting business goals.

Most recently, I was Head of Design at Tech Alchemy, one of the world's leading blockchain agencies. I led a team of ten across product, graphic, and motion design, owning design vision across 15+ concurrent client engagements, from early-stage startups through to enterprise leadership teams.

I've worked with founders, product teams, and growing technology businesses across Web3, fintech, AI, B2B SaaS, and consumer products, designing intuitive user experiences and building scalable design systems that help products move faster and stay consistent.

I'm now working independently, partnering with teams that need senior craft and clear thinking. I'm also building AI-assisted design workflows with Claude and Claude Code, closing the gap between concept and working prototype.
