About
Gerrit Halfmann
Full-stack designer and developer. Building for the web since 2005. Based in Poland, working with companies across Europe and the US.
I design, build, and optimize websites as a one-person studio. That means no handoffs between a designer, a developer, and an SEO consultant. I do all three, which makes things faster, more coherent, and less expensive than the alternative.
When I'm not working on client projects, I build my own products. I've created icon libraries used by thousands of developers, SaaS tools for AI visibility and apprenticeship training, and free utilities that solve small problems well. I think the best way to understand what founders need is to be one.
What I do
Design
UI/UX, branding, design systems. Figma-native, dev-ready deliverables. Clean, purposeful, fast.
Development
Astro, Next.js, Tailwind. Static sites, web apps, component libraries. Performance-first.
GEO + SEO
Search optimization for Google and AI engines. Structured data, citability, technical SEO, AI crawler access.
AI Agents
Automated weekly audits for marketing, competitors, content, and social. Powered by Claude.

Products I've built
I don't just build for clients. I build my own things. It keeps me sharp, teaches me what founders actually need, and proves I can ship.
