Recent work: a full RLS security audit and hardening pass on a production Supabase backend. A 410-test Playwright suite on a Next.js portal. A Postgres outbox pattern for reliable async side effects. 100% Job Success across 22 jobs. Most clients come back for a second project. I lead with specifics because anyone can claim "clean code and great communication." Specifics are harder to fake. I'm a senior Flutter developer (10+ years mobile, 7+ in Flutter) based in the Netherlands, working with startups and scale-ups across Europe. Three ways I'm probably different from the other profiles you're comparing: 1. I'm genuinely full-stack. Flutter is my core, but I regularly own the whole system: Next.js portals, Supabase/Postgres (including RLS security audits and migrations), Hono/Bun backends, CI/CD, TestFlight releases. You don't need a second freelancer for the backend. 2. My AI work is in production, not in demos. LLM APIs, semantic search with pgvector, RAG pipelines shipped as real features users pay for. If you want AI that's actually useful in your product rather than a chatbot bolted on, I've done it and can show you. 3. I work like it's 2026. I run AI-assisted, multi-agent development workflows daily, which means senior-level architecture decisions delivered at a pace solo developers couldn't match a few years ago. You get speed without the usual speed/quality trade-off. What I've shipped: fintech and crypto apps, large-scale e-commerce, enterprise onboarding, social apps, inspection/field-service SaaS. Architecture through App Store submission, every time. Stack: Flutter & Dart · Riverpod & BLoC · Firebase & Supabase · PostgreSQL + pgvector · TypeScript / Next.js / Hono / Bun · OpenAI & Anthropic APIs · Fastlane, CI/CD, Playwright Where I fit best: 📱 Greenfield builds - architecture to App Store 🤖 AI features - summaries, semantic search, chat, recommendations 🚑 Rescues - performance problems, state-management messes, codebases left behind by a previous dev 🧪 Hardening - testing, refactoring, security audits, code review How I work: clear, proactive communication, you'll never wonder where things stand. Documented code with tests, because whoever maintains it after me deserves that. And I don't need hand-holding: point me at a problem and I'll own it end to end. If your project needs someone who can think about the whole product, not just the Flutter layer, send me a message and tell me what you're building.
