01 / About
Engineer by craft,
builder by instinct.
I'm a Senior iOS Engineer at CBH Bank (Switzerland), where I own the Cards domain and the bank's reusable Cards SDK shared across three consumer apps — secure authentication, certificate pinning, 3DS flows, the whole deal.
Before banking I built for scale and for fun: face-swap features at Reface (5M+ MAU), a real-time claw-machine game at Clawee streaming WebRTC to a million users, an AR music app that turns your body into an instrument, and a food-delivery platform from scratch for 500K+ users.
Started with Swift 2.3 and iOS 8. One thing those years taught me: quality at scale matters.
- 🧠 Architecture & modularization
- 🧰 SDKs & internal tools
- 📱 From-scratch app development
- 🎨 Complex UI & animations
- ⚙️ Reactive programming
- 🧩 AI integration
02 / The Studio
redmilk.ai — where AI meets product.
My studio for AI-first product engineering. From architecture to shipped app — one accountable brain, agent-orchestrated execution.
📱
Mobile App Development
Native iOS in Swift & SwiftUI, built from scratch or rescued from legacy — banking-grade security included.
🎨
Design Solutions
Product design, motion and brand systems that feel like candy and convert like machines.
🤝
AI Integration for Business
Plugging LLMs into real workflows: support, content, ops. Measured by outcomes, not hype.
⚡️
Automation
Pipelines that remove humans from repetitive loops — CI/CD, content generation, back-office flows.
🎮
Game Development
Interactive mechanics and real-time experiences — from AR sound games to remote-controlled machines.
