Mark Darling

Hi, I'm Mark Darling,

Digital Innovator | Engineering Leader | Reluctant Perfectionist

I'm passionate about turning complex problems into simple, scalable solutions. Currently, I lead mobile engineering efforts at Gymshark, focusing on clean architecture, observability, and transforming tech debt into opportunities for growth.

My experience spans web development, mobile engineering, and driving business automation through AI-powered solutions. I've shipped apps, built high-performing teams, and developed tools that streamline workflows and unlock new efficiencies. Along the way, I've earned a reputation for bridging the gap between technical depth and business impact—always with a focus on delivering real value where it matters most.

Whether it's optimising mobile apps or leveraging AI to automate processes, I believe technology should enhance lives, not complicate them. Let's build smarter, not harder.
