My Working Style

Clear Communication

I tell it like it is. Even when it's uncomfortable. No buzzwords, no inflated presentations.

Pragmatic Solutions

The best for your situation, not the most expensive. IT should do its job, not be an end in itself.

Hands-on Mentality

I don't just sit in meetings, I also do the work. From strategy to configuration.

Reliability

What I promise, I deliver. On time, on budget, at the agreed quality.
