I'm Marik Brestovitsky. I lead global IT at Rakuten Viber and build tools like Pika and Kot. I also co-founded Computer from the Heart and serve as its Chairman.

A Hebrew-first assistant for WhatsApp and Telegram. Text and voice, reminders and Google integrations, with approval before sensitive actions. Built to make everyday tasks easier.

A Hebrew recipe app designed to collect recipes from links in one place. Current work focuses on reliable imports and preserving the ingredients and instructions.
I'm a co-founder and the Chairman of Computer from the Heart. See the social impact section below for the work behind it.
In Israel, many children lack access to a computer because their families can't afford one. In today's world, that means falling behind in education, communication, and opportunity. Once that gap opens, it's incredibly hard to close.
I co-founded "Computer from the Heart" (מחשב מהלב) to bridge this digital divide. We collect functional computers that companies consider "obsolete" when upgrading their hardware, refurbish them with our volunteer tech team, and deliver them to families and individuals who need them most.
It's the most meaningful thing I do with my technology skills: making sure that every child has access to the tools they need for an equal chance.

I'm Marik Brestovitsky, an IT Director and technology builder based in Israel. Before any job title, I'm a husband and father of three. I like understanding how things work, whether that means taking something apart or building a tool from scratch.
Today, I lead global IT at Rakuten Viber, mentoring regional leads and overseeing budgets, SaaS governance and IT operations across five countries. At Rapyd, I rebuilt the IT team, hired across multiple countries and led IT and security in a regulated fintech environment.
Earlier roles at Check Point, ironSource, Snyk and Viz.ai shaped my approach to hiring, coaching and giving teams clear ownership. I bring that experience to mentoring IT leaders and building departments, connecting people, engineering and business priorities.
Husband and father of three. They're the reason I work hard, and the reason I know when to close the laptop.
I've been taking things apart since I was a kid. Hardware, software, networks: I enjoy understanding how things work.
Music is the background to everything I do: coding, thinking, unwinding. A good playlist can fix almost anything.
Somewhat competitive car racing enthusiast. The precision and focus of racing isn't that different from a production deploy at 2 AM.
IT professionals moving into their first management role, and current managers who want to develop their leadership. We can work on delegation, feedback, team development, communication with executives or your next career step.
Mentoring focuses on you as a manager and the decisions you face. Department development focuses on the organization: team structure, roles, hiring plans and working processes. We can define the focus together if your challenge involves both.
Yes. Your starting point might be a new management role, a first IT hire or a change in team structure. In an introductory conversation, we can explore the challenge and discuss what kind of support would fit.
