Senior Front End Engineer at CrowdStrike
Hi, I’mGilad Madar.
I build interfaces for a living. Today that means front end at CrowdStrike, after stops at AI21 Labs, Dropbox, Intuit, VisualDNA and Infolinks.
After hours I build price trackers and small tools. The longest-running, Handz, has been watching Yad2 prices since 2015 and grew to 35K users.
