Customer Success IT Management AI Engineering Independent project work
Customer Success engineering, IT management, and applied AI — built and operated end-to-end.
Seventeen years across customer-facing engineering, IT management, and applied AI — the same person can scope the problem with the team, build the system, and operate it in production.

01 / About
A builder who also knows how to operate.
I'm a systems engineer and IT manager with 17+ years across the customer-facing side of enterprise software — Malam tech support, Secure Islands post-sales engineering, Microsoft Premier support, Claroty Tier 3 escalations, and IT management at Profero. The through-line is close-to-the-customer, close-to-the-system work, with personal accountability for the outcome from scoping to production.
Alongside that, I build applied AI systems, automations, and internal tools — often Hebrew-first, almost always tied to a concrete business problem. The differentiator is the intersection of three things that usually live with three different people: knowing the customer, understanding the operational reality, and being able to engineer.

Long (~150 words)
Yishai Kaminsky is an IT manager and systems engineer who has spent 17+ years working at the intersection of customer-facing engineering, IT and operations, and applied AI. His professional roles span Microsoft (Premier-tier customer support), Secure Islands Technologies (post-sales engineering for international financial and legal institutions), Claroty (Tier 3 escalations for an OT/IoT cybersecurity platform), abra (multi-client cloud IT and security services), and Profero (IT management at a cyber incident-response firm). Alongside professional roles he builds practical AI tools and automations — including TailorCV, a CV-tailoring assistant with built-in fabrication guards, and whatsai, a small AI persona chat experiment. He cares about reliability — logging, permissions, fallback paths, and human approval where it matters — and prefers durable solutions over fragile demos. Bilingual in English and Hebrew. Based in Israel; open to full-time, hybrid, remote, or on-site work in the Tel Aviv area.
