How I work & pricing
Rate: from €125 per hour, 1 hour minimum.
First intro call is free. Book directly via cal.com/nickbouwhuis.
You pay for expertise, not typing speed
Experience means efficiency. Pattern recognition from years of production troubleshooting means faster root cause analysis. You pay for the solution, not for search time.
1 hour minimum, then hourly
No half-day blocks, no mandatory packages. Billed per hour, with a 1 hour minimum per engagement.
Not the cheapest option
If price is your main concern, I'm probably not the right partner. If reliability and expertise matter, I am.
