Summary
Erik Tjernlund is a senior iOS and macOS engineer with 14 years of experience, currently contracting at Apple and running his own consultancy, Klartek AB, from Stockholm. He designs and ships high-performance native apps and low-level communication stacks—most notably architecting SVTPlay’s Swift-based client used by millions and building sensor network protocols for marine tech. Comfortable across Swift, Objective‑C, AppKit/Cocoa, Combine and SwiftUI, he excels at energy- and network-efficient client architectures that tolerate poor connectivity. A pragmatic founder and long-time consultant, he pairs deep systems experience (from Java enterprise and PKI work to Unix ops) with a knack for shipping production-grade products in constrained environments. Notably, he’ll travel for the right Xcode-powered mission.
