He possess expertise in distributed systems, cloud computing, mobile devices, computer security, javascript and 23 more skills. Colleagues describe him as "Ari is quite simply a fantastic engineer and an awesome guy. I can't stress enough how much I enjoyed working with him at Centrify. Ari was quick to find the light side of stressful situations, and always kept a level head. Ari was also the key to quickly creating and bootstrapping new features which cut across a large and complicated code base. His ability to dig in fast, and generate a prodigious amount of good code in a short period of time was instrumental in pushing us past several barriers. It didn't seem to matter that a feature required mobile, backend, JS *and* build process changes; Ari efficiently cut through all layers to achieve success. I learned a lot from my time working with Ari, and continue to value those lessons highly." and "Ari has a rare quality among software professionals in that he posses extreme technical competency, all the while being humble and easy to work with. Regardless of what the issue or question, regardless of the time or other 'priorities', Ari can be counted to be available and a team player. I enjoyed working with Ari on the Windows Security team, and I'm sure everyone else would say the same."
