Hire the Best iOS Developers
in the Netherlands

I am an Data Analyst with a background in Computer Engineering. I love digging into the "why" behind the numbers, using tools like Power BI, SQL, Python, and Azure to turn complex data into clear insights. I’m a social person who thrives in fast-paced environments. I am a very fast learner—a great example is my Dutch language journey: I've followed an intensive program and reached the B2 level (NT2-II) in just 16 weeks!

I design and build apps end to end, from first concept to a live product. iOS first: native SwiftUI apps, designed, built, and shipped to the App Store by one person. But not iOS only: I also build the backends, APIs, and web pieces your product needs to actually run. Most projects need a designer, a developer, and someone to manage the gap between them. With me there is no gap. The person who designs your screens is the same person who ships them, so nothing gets lost in handoff and decisions take minutes, not meetings. WHAT I BUILD • Native iOS apps in SwiftUI, from scratch to App Store release • Redesigns and rebuilds of existing apps • Backends and APIs when your product needs them (Python, FastAPI, Supabase, PostgreSQL) • Web apps and landing pages when your product needs a website • Subscriptions and paywalls done right (StoreKit 2, RevenueCat) • Onboarding, analytics, and attribution set up for growth • AI features where they add real value: chat, assistants, recommendations (Claude, OpenAI) HOW I WORK Clear communication, fast iterations, honest estimates. My track record on Upwork says the same: Top Rated, 100% Job Success across 30+ completed projects. A GOOD FIT IF YOU NEED • A new app designed and built by one person, start to finish • An existing app polished, extended, or rebuilt • An MVP shipped fast to validate an idea • AI features added to your product Tech: Swift, SwiftUI, StoreKit 2, RevenueCat, Python, FastAPI, Supabase, PostgreSQL, REST APIs, OpenAI API, Claude API, App Store Connect Send me a message with what you are building and I will tell you honestly what it takes to ship it. Hope we will connect soon!

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.
