§00 / COVER

For recruiters, hiring managers, and teams looking for a practical builder

Practical AI systems, automations, and internal tools — grounded in real IT, infrastructure, and operations.

I build systems that help teams move faster, reduce friction, and turn operational complexity into workflows people can actually use.

§01 / ABOUT

A builder who knows how to build and how to operate.

I'm an IT and systems professional with 17+ years focused on turning complex operations into reliable, practical workflows. My background spans IT leadership, cloud services, cybersecurity, enterprise support, and hands-on delivery across organizations like Profero, abra, Claroty, Microsoft, and Secure Islands.

Alongside the professional work, I build AI-powered tools, automation systems, and Hebrew-first products. The differentiator is not just AI and not just IT — it is the combination: taking real operational problems, translating them into useful systems, and connecting automation, infrastructure, and delivery that can actually run.

01

Applied AI, not demo AI

Focused on systems that help teams operate — not flashy prototypes or one-off chat experiences.

02

Systems thinking

Find bottlenecks, map workflows, and build internal tools that reduce friction and improve execution speed.

03

Real infrastructure depth

Hands-on experience from enterprise environments — senior support, cloud, security, and technical operations.

§02 / SELECTED WORK

A small set of proof — work and code to be evaluated by.

Instead of a generic gallery, a few projects and repositories that best demonstrate systems thinking, implementation depth, and the ability to connect AI to real operational work.

§03 / EXPERIENCE

A long arc of IT, enterprise support, cloud, and technical operations roles.

This history matters because it reduces the gap between idea and production reality — the current AI and automation work sits on a real operational foundation.
