IT leadership for startups
that are ready to grow.

As your team grows, IT needs to grow with it. I help startups plan infrastructure, manage access and devices, and reduce manual work, with support shaped around their needs.

vCIO: Virtual IT Leadership

Turn competing IT needs into a clear roadmap, with infrastructure priorities, vendor decisions and budget planning.

Managed IT & Helpdesk

Make joining and leaving the company simpler through account access, device setup and ownership of support issues.

Cloud Migration & Architecture

Plan cloud moves around your applications, access needs and operating costs, then carry out the agreed migration.

AI & Automation

Find repetitive work worth automating, build a small working version and check it against the actual workflow.

Security Foundations

Review identity, permissions and device protection, then prioritize practical improvements to your security baseline.

Giving Back

Co-founder and chair of Computer from the Heart.

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.

My Story

The person behind the terminal.

I'm Marik Brestovitsky, an IT Director and technology builder based in Israel. Before any title, I'm a husband and father of three kids who keep me grounded, honest, and usually sleep deprived.

I've been curious about how things work since I took apart my first computer as a kid. That curiosity became a career: over 15 years building infrastructure, security, and cloud systems, currently leading IT at Rakuten Viber. I believe technology only matters when it actually serves people.

On the side, I build things that solve real problems, like Pika, Kot, and Kometz. I'm also co-founder and chair of Computer from the Heart, a nonprofit that refurbishes computers for families who can't afford one, because every child deserves a fair shot.

- Marik

Family First

Husband and father of three. They're the reason I work hard, and the reason I know when to close the laptop.

Tech at Heart

I've been taking things apart since I was a kid. Hardware, software, networks; I just genuinely love understanding how things work.

Music Lover

Music is the background to everything I do: coding, thinking, unwinding. A good playlist can fix almost anything.

Track Days

Somewhat competitive car racing enthusiast. The precision and focus of racing isn't that different from a production deploy at 2 AM.
