About
Radomir — Fractional CTO | Mobile, MedTech & Connected Products | Novi Sad, Serbia
I'm a fractional CTO and principal engineer with over 12 years of experience leading software delivery for companies in Germany, Switzerland, the Netherlands, Austria, the UK, Italy, Israel and the USA. Since 2014 I've run engineering at Digital Atrium, building and leading in-house iOS, Android and backend teams that have shipped products in the medical, industrial, fintech and consumer sectors.
My background includes regulated medical device software (IEC 62304, FDA compliance), BLE-connected hardware, native iOS architecture, cross-platform mobile (Flutter, Kotlin Multiplatform), and Node.js/NestJS backends on AWS.
I step in as a hands-on technical leader. I set architecture and technical strategy, take products through regulatory requirements, structure and scale engineering teams, and make sure technology decisions serve business goals.
I hold an MSc from the Faculty of Technical Sciences, Novi Sad, and am completing my PMP certification.
