About Me

Engineer, Builder, Founder — Ron Tabachnik, Software Engineer & Founder of Digitab (OnlinePixels), Israel

I'm an iOS and full-stack engineer who turns hard problems into products people actually use. My path started far from a keyboard, as a medic and instructor with Magen David Adom, where I still volunteer today. From there I earned an informatics degree at Kaunas University of Technology and spent years shipping production apps across fintech, sports, automotive, and my own ventures. Today I split my time between mission-critical banking infrastructure and Digitab (OnlinePixels), my product studio behind ClinicHub, iZicards, and more.
