Hi, I'm Henry Okonkwo, a Senior Frontend Engineer based in Berlin. I specialize in TypeScript and modern frontend architectures (React/Next.js, Vue 3/Nuxt 3), focusing on performance, accessibility, and scalable UI systems. I’ve built and scaled SaaS products across fintech, developer tooling, and events, and recently led a Nuxt 2 to Nuxt 3 migration and shipped an AI-powered support chat across three surfaces. I’ve launched consumer AI products on Anthropic Claude (DocGate, Sprevia) and designed end-to-end experiences that turn chats into qualified leads while maintaining maintainable code and design system alignment. I enjoy building robust CI pipelines, analytics taxonomies, and AI-assisted tooling to improve reliability and velocity.…Hi, I'm Henry Okonkwo, a Senior Frontend Engineer based in Berlin.
