For HalloPetra — an AI phone assistant for small businesses — I designed the UI and UX, built the component library in Figma, and created the core screens across the app. The main work went further: with Claude Design and Claude Code, I turned the design language into a single design.md spec that Claude Code reads directly. The client's team can now ship new features in the correct design system from day one — no designer in the loop. A design system that scales on its own.

Working with Julian was exactly what our product needed. He designed the entire UI and UX for HalloPetra and built us a component library and a design system that our team can now build on ourselves — new features ship in the right design from day one, without a designer in the loop. Thoughtful, fast, and genuinely forward-thinking.

Julian's work on Melty was spectacular. The design was rich and engaging, perfectly capturing our brand's essence. His blend of aesthetic appeal and practical functionality sets him apart. We are thrilled with the results and highly recommend his services to anyone seeking unique and impactful design.
