Led by Experience

Roman Sakhnievych

Founder & CEO

After more than a decade in iOS engineering, I founded Devios to solve a recurring problem: companies need senior Apple expertise, but building and maintaining such teams internally is expensive and slow. We provide that depth of expertise without the overhead — delivering focused, high-quality native solutions across the Apple ecosystem.

"We don’t try to do everything. We focus on Apple — and we do it exceptionally well."
