Yosi Fridman
Independent technology consultant and tech lead with over 20 years of experience in large enterprises and the public sector. I lead projects from the first requirement to a system running in production: S/4HANA and BTP upgrades, cloud architecture, integrations, full-stack development and AI solutions.

20 years across every layer of the stack
I started as a network administrator in the IDF, moved into IT infrastructure, led full-stack development at an international company, and served as tech lead on projects in government, healthcare and transportation. Since 2024 I've been independent, leading S/4HANA, BTP and AI projects.
That mix – infrastructure, integration, development and cloud – lets me see the full picture and build solutions that fit properly into an organization's existing systems.
