About Mariusz

Mariusz S.Status: Offline
Solo Expert iOS Developer | iOS MVP Apps | AI Integrations
Nuernberg, Germany - 12:18 am local time
Native iOS apps. No shortcuts. No agencies BS. I work directly with startup founders and SaaS teams who want to ship real iOS products. Not demos held together by templates, no-code tools, or cross-platform compromises.
I build native iOS apps in Swift and SwiftUI, focusing on:
• fast MVPs
• clean architecture
• long-term code ownership
• direct, founder-level collaboration.

If you’re:
– thinking how to build your iOS app
– worried about technical debt before v1
– rebuilding after no-code or cross-platform disasters
– or want clarity before hiring a developer
I'm the right guy.

Ready to build the real thing?
Share a few details and I’ll respond within 1–2 business days with clear next steps.
