Tech advisory without the overhead

You get a senior engineer's perspective — without a senior hire's salary. I help you hire right, pick the right tools, and avoid building things nobody needs. Every engagement starts with a conversation to see if there's a real fit.

Engagement

What this looks like in practice

Pricing

Daily rate

€1.6k/day

For focused sprints — architecture reviews, migration planning, or deep-dive assessments. One "day" means 8h of my time, stretched across 1–2 weeks — not a full consecutive day. Discount available for 5+ days.

I hold a full-time role alongside this practice, so my availability is focused and intentional — primarily evenings and weekends. Every engagement starts with a free scoping call to make sure it's a real fit.

Free call → fit check

You describe your situation, I ask questions and review offline. We decide together whether to move forward — or I refer you to someone better suited.
