About Martin

I’m a senior software developer with 20+ years of experience, focused on Apple platforms (iOS, iPadOS, macOS, watchOS, tvOS).

I’ve worked with a wide range of organizations—from early-stage startups to large industrial companies—on projects spanning medical software, e-commerce, mobile games, utilities, and e-mobility. I enjoy collaborating in teams, but I’m equally comfortable delivering complete solutions on my own.

I can take a product from idea to App Store: I’ve done it repeatedly with my own apps and by helping clients bring brand-new concepts to life.
