Google DeepMind (2026 - Present)
I work as a Research Scientist at Google DeepMind, focusing on AI research.
Apple (2017 - 2026)
Prior to DeepMind, I spent over eight years at Apple as a Principal Engineer and Technical Lead. My work spanned applied machine learning and large-scale cloud infrastructure—leading developer-facing AI tools, building generative AI developer experiences and communities across the company, and engineering resilient backend systems and data synchronization for Apple's ecosystem.
Distributed Systems Researcher (2013 - 2017)
I received my BSc in Software Engineering (2010) and Ph.D. in Distributed Systems (2017) from the Technion – Israel Institute of Technology, advised by Prof. Idit Keidar. My academic research focused on distributed computing, concurrency, and algorithmic correctness (an article in Hebrew about my wife and me after completing our doctorates).
During my graduate studies, I spent summers interning at Google and Yahoo! Research. Before my Ph.D., I was a Software Engineer at Wanova (acquired by VMware).
The Whole of You
What if the thing you've been searching for your entire life is actually nothing at all?
For an unknown reason, I had to write a book about it.
Yes, about nothing.
Things you can do with this book
The Whole of You is an unconventional, blunt, and deeply playful exploration of non-duality and raw awareness, attributed to "By Nothingness through Kfir Lev-Ari".
Visually and structurally unique, the book's text literally dances around a physical die-cut hole running through its center, serving as a constant, three-dimensional metaphor for the reader's true identity. It's not just a book; it's a "holey book" designed to mirror the formless reality that exists prior to thought.
Refusing to be another standard self-improvement guide, The Whole of You actively dismantles the myth of the ego. It handles complex metaphysical concepts with a refreshing mix of sharp philosophy, biting humor, and unfiltered sincerity. Through striking analogies, the book invites you to stop looking for yourself among the temporary contents of your life story.
"Let me take you away from them, away from what you think you are, so you will find it. There's nothing to find."
Key Themes Explored
The Ego as a Process
Realize that the collection of memories, fears, and stories you call "you" is simply a sequence of pictures playing on a tape to maintain the illusion of consistency.
The Trap of Sticky Words
Learn how the mind builds intellectual cages out of concepts like "oneness" or "positivity," obscuring the effortless simplicity of just Being.
The Ultimate Spoiler
Discover that at the end of everything, there is nothing, which was everything in the first place.
Perfect for readers familiar with classic non-dual teachings but craving a radically direct, conversational, and sometimes beautifully inappropriate approach. The Whole of You won't fix your life story, because it reminds you there is nothing to fix. It is simply a mirror showing you that you are the background space in which the entire world is dancing.

QuiCK: A Queuing System in CloudKit
SIGMOD, 2021
As part of my work in the ACS Applied Research Team, I was the TL of QuiCK - a queuing system built for managing asynchronous tasks in CloudKit, Apple's storage backend service.
It was a great experience working on QuiCK and bringing it from idea to production at scale.

FairLedger: A Fair Blockchain Protocol for Financial Institutions.
Best Paper Award
OPODIS, 2019
Working closely with Sasha (Alexander) on this was a fantastic journey. Back in the days when blockchain (i.e., a shared distributed history) was the fastest emerging topic in the neighborhood, we asked what it would take for selfish players to run such a protocol fairly.
Our answer was this work.
Composing Ordered Sequential Consistency
Inf. Process. Lett., 2017
While taking a small break to sleep while working hard on the proof for our "Modular Composition of Coordination Services" paper, I remember not letting go of thoughts about possible execution histories. Then, out of nowhere, I realized I could generalize two known correctness criteria under one definition (linearizability and sequential consistency) and prove the composition of that new abstraction.
It was a small win, but my favorite one in my Ph.D.
Slicer: Auto-Sharding for Datacenter Applications
OSDI, 2016
On my first internship at Google, I received a task to design a new load-balancing algorithm for Slicer - Google's internal Sharding-As-A-Service system, replacing an existing variant of consistent hashing in use.
We designed a generic algorithm that we named “Weighted Moves” - the idea was to evaluate a few types of small load changes iteratively (i.e., “moves”) with respect to a user-defined cost function and to make progress as long as there's an allowance for them.
Modular Composition of Coordination Services
USENIX ATC, 2016
I received this project during my internship at Yahoo! Research. The initial goal was to design and implement a way to work with multiple instances of ZooKeeper while maintaining the semantics.
I started by examining ZooKeeper and learning its internals. Then, we identified possible improvements in ZooKeeper's performance and contributed them to the project along with a system test that generates corresponding workloads.
For the construction of multiple instances, we proposed the modular composition approach, a client-side solution that I really liked.

Photography
Nowadays, photography for me is less of a hobby and mostly taking the smartphone out and capturing the kids doing amusing things, but I remember a time that photography was much more than that! (also weighted more! a DSLR camera isn't great fun to walk with for a couple of hours…).
