Senior Apple Platform & Product Engineer · Berlin, Germany
Building privacy-first Apple products powered by modern Swift and intelligent technologies.
Senior Apple Platform & Product Engineer with 16+ years of experience. I build privacy-first iOS and macOS applications, ship full-stack web products, and integrate AI into real user experiences — from Swift to Next.js, CoreML to Claude.
How I work
Engineering principles
Simple over clever.
The best solution is usually the one a teammate can understand six months from now without a walkthrough. I optimize for clarity first and reach for abstraction only when the codebase has earned it — not before.
Privacy by default.
Data you never collect can never leak. I design systems that keep sensitive information on-device wherever possible, encrypt what has to leave it, and treat every permission prompt as a promise to the person granting it.
Performance matters.
Speed is a feature, not an afterthought. Jank, cold-start delay, and dropped frames erode trust faster than a missing button — so I profile early, budget for the worst device in the fleet, and treat regressions as bugs.
Accessibility is essential.
A product that only works for some of its users isn't finished. VoiceOver, Dynamic Type, and reduced motion aren't edge cases to me — they're part of the same craft as the pixel-perfect layout.
Selected work
Products I've built
Independent · 2021 — Present
Momena
A privacy-first consumer app I designed, built, and shipped entirely by myself — from Figma to SwiftUI, CloudKit sync, and weekly AI-powered insights — without operating a traditional backend.
Independent · 2024 — Present
Momena — Marketing Website
Designed and built the full marketing website for Momena from scratch — multilingual content (EN/TR/DE), blog infrastructure, SEO, and App Store landing page. No templates, no page builders.
Magnosco · 2023 — Present
Magnosco — Diagnostic Imaging Platform
The iOS application connecting a dermatological imaging device to an on-device CoreML diagnostic pipeline, built in close collaboration with imaging scientists.
Writing
Notes on building
Building Products as an Engineer
Founding Momena taught me things about product thinking that sixteen years of writing Swift never did. Here's what changed once there was no one else to hand the decision to.
Lessons from 16 Years of Apple Development
What actually changed my mind about building software, from Interface Builder to SwiftData — and what stayed constant the whole way through.
LLMs Inside Native Apps
Bringing language models into a privacy-first Swift app without turning it into a chatbot wrapper — scoped prompts, honest UI, and knowing what to keep on-device.
Have something worth building?
I'm always glad to talk through a hard engineering problem — Apple platform architecture, computer vision, full-stack product work, or turning a research prototype into something people actually use.
