01/ About me

Hello,
I'm Malcolm

Husband. Father. I play football every week, rain or shine. Off the pitch, I'm usually gaming, planning the next trip, or finding a new restaurant to try. Easy-going by nature and solutions-focused at work, I genuinely enjoy helping the next generation of engineers find their feet.

I'm a senior iOS engineer with over 10 years of experience building and modernizing mobile products. My work runs deep in Swift, UIKit, and SwiftUI, with a strong focus on architecture, platform scalability, and shipping things that hold up under real-world use.
