About Nandor

Nandor Katai founded iFeeltech in 2003 with a straightforward goal: make business technology work the way it should — reliably, securely, and without unnecessary complexity. Over more than two decades, that mission has shaped an IT practice that now serves over 100 businesses across Miami-Dade and Broward Counties, with a 4.9/5 rating on Google.

His day-to-day work spans network infrastructure design, UniFi enterprise deployments, structured cabling, cybersecurity implementation, and managed IT support for growing companies. He has worked directly in client environments across healthcare, professional services, logistics, and retail — giving him a ground-level view of where technology friction actually occurs, not where it appears in textbooks.

That practitioner perspective drives how he writes. Every guide, review, and comparison on iFeeltech's blog reflects real implementation experience: the configurations that hold up under load, the tools that deliver what they promise, and the common mistakes businesses make when managing their own infrastructure.

In 2025, Nandor launched Valydex — a free cybersecurity assessment platform built on the NIST Cybersecurity Framework 2.0. The tool grew out of a pattern he kept encountering with clients: most businesses understand that security matters, but struggle with where to start. Valydex translates the NIST framework into a structured, accessible assessment that generates a prioritized action plan in under five minutes.

He is based in Miami, Florida, and available for IT consulting engagements through ifeeltech.com.
