Sahin Raj

Senior iOS EngineerSwiftUI • SwiftData • iPadOS • Performance

Senior iOS Engineer and technical leader with 10+ years of experience, including 5+ years architecting large-scale enterprise iPad applications. I focus on clean SwiftUI architecture, strong data layers, and measurable performance in production-critical systems.

Focus

What I build

SwiftUI Architecture

MVVM, shared app state patterns, modular design, maintainable UI composition.

Data & Persistence

SwiftData / Core Data, caching strategies, efficient querying and data flow.

Performance

Large lists/grids, view decomposition, reduced recomputation, main-thread minimization.

Modern iOS Integrations

Widgets, App Intents, notifications, background processing in secure enterprise environments.

Work

Featured projects

Compass (iPad)

Enterprise iPad app supporting operational workflows with dense, multi-day scheduling UI and performance-sensitive interactions.

  • Architected scalable SwiftUI patterns and shared app state for cross-module consistency.
  • Improved UI responsiveness by reducing recomputation in large lists/grids and minimizing main-thread work.
  • Built resilient networking flows with robust error handling and partial-data tolerance in secure environments.

Details are described at a high level due to enterprise confidentiality.

HealthWay Digital

A healthcare-focused digital product experience (portfolio item).

SwiftUIArchitecture / PatternsNetworkingUX
  • Showcases clean architecture, modular UI, and strong UX fundamentals.
  • Structured as a product-style case study with clear problem/solution framing.
  • Great candidate for screenshots and a short walkthrough video/gif.

Send me 4–6 bullets of what it does and I’ll turn this into a stronger case study with no fluff.
