Rockstar🎓
Top SchoolMoustafa Berg is a seasoned technology leader and hands-on iOS engineer with 11 years of experience, now serving as CTO in Trondheim, Norway. He has led teams at Telenor and built mobile firmware and BLE tooling at Nordic Semiconductor, contributing to well-known projects like the iOS DFU library and nRF Toolbox where he strengthened OTA reliability and CGM features. Equally comfortable in leadership and code, he has a track record of improving robustness and test coverage in open-source Swift projects (notably fixes for file-permission handling in a popular Zip framework). Early full-stack web work in Egypt taught him to design for high availability and payment-linked systems, a practical mindset he still applies to product and infrastructure decisions. Outside work he’s an avid game builder and tinkerer, blending creative prototyping with pragmatic engineering. Colleagues know him as a pragmatic problem-solver who pairs strategic vision with attention to low-level reliability and developer experience.
