About

I’m Demian Turner, a product-focused tech leader and entrepreneur who’s built and scaled engineering teams, launched profitable ventures, and delivered high-impact iOS/macOS apps used worldwide. I’ve grown mobile teams from scratch to 20+ developers, cut compile times by 65%, boosted test coverage to 80%, and consistently shipped polished Apple platform apps for global clients.

Alongside leading startups—bringing dozens of apps to market, including several App Store #1s—while running lean, profitable operations. I remain deeply hands-on as a senior iOS engineer, writing production Swift daily and architecting both front-end and back-end systems. Recently, I’ve been shipping AI-powered apps using models from OpenAI, Anthropic, Google DeepMind, Microsoft, and Perplexity AI.
