Hire the Best Flutter Developers
in the Netherlands

Flutter specialist based in the Netherlands. I've been building mobile and desktop apps for over 10 years, mostly for startups and scale-ups across Europe. Lately I've gone deep on AI integration: LLM APIs, semantic search with pgvector, RAG pipelines. Not as experiments, but as shipped production features. If you want someone who can add genuinely useful AI to your app, not just a chatbot wrapper, I've actually done it. What I've shipped: Fintech and crypto apps, large-scale e-commerce, enterprise onboarding tools, social apps. Always from architecture through to App Store submission. My core stack: Flutter & Dart · Riverpod · Firebase · ObjectBox · TypeScript / Hono / Bun · PostgreSQL + pgvector · OpenAI & Anthropic APIs Where I can help: 📱 Build from scratch: architecture to App Store, start to finish 🤖 Add AI features: summaries, semantic search, chat interfaces, recommendation engines 🐛 Fix what's broken: debugging, performance, state management 🎨 Level up the UI: polished, responsive, feels native on every platform 🔍 Code review & refactoring: clean architecture, testing, documentation How I work: I communicate clearly and consistently. You'll always know where things stand. I write well-documented code with unit tests, because whoever maintains it after me deserves that. I'm not the kind of contractor who needs hand-holding. Point me at a problem and I'll own it.
