Jun G.

✨ Expert-Vetted Senior iOS Engineer by Upwork | Honored to be among the Top 1% of Global iOS Talent. I am a Product-Minded Engineer with over a decade of system development expertise, specializing in High-Fidelity Native iOS since 2016. My career is defined by high-standard iOS app execution—notably independently architecting the iOS Home & Lock Screen Widgets for Edison Mail (4.5+ stars), which earned a prestigious App Store Editorial Feature. 🚀 🏗️ My Engineering Standards: • 💎 Pixel-Perfect Craftsmanship: I treat Figma designs as a baseline for excellence. I specialize in building fluid, state-driven interfaces with custom animations, haptic feedback, and complex gesture systems—ensuring every interaction feels premium. • 🤖 AI-Native Development: I leverage modern AI orchestration (MCP, Cursor Rules) to accelerate development cycles while maintaining high code quality. I build systems that are architected to be AI-ready from the ground up. • ⚙️ Scalable System Design: With a strong foundation in large-scale engineering, I prioritize Modern Concurrency (Actors/Task Groups), memory optimization (Instruments), and modular architecture to ensure long-term maintainability. • 🛠️ Full-Stack Perspective: Beyond Native iOS, I am proficient in architecting the entire data lifecycle—from Supabase/Postgres schema design to complex backend integration. I bridge the gap between high-performance data logic and seamless mobile UX. 💬 What Clients Say: • "Jun delivered solid work and went the extra mile for the UX.
