Senior technical consulting for complex IT

Your IT doesn't have to be simple.
But you need to understand it.

I analyze complex, grown IT environments, uncover hidden dependencies and technical risks, and create a clear path forward — before change turns into disruption.

01 — SYSTEM HEALTH

Does this sound familiar?

The system works — but nobody wants to touch it because nobody is completely sure what will happen.

01

Knowledge has left

The people who built critical parts of the system are no longer available.

02

Documentation ≠ reality

Diagrams and documentation describe only part of what actually runs in production.

03

Changes feel dangerous

Updates and migrations are postponed because their side effects are unknown.

04

Backups are assumed

Jobs are green, but a full business-critical restore has never been proven.

05

Providers blame each other

Application, network, database and infrastructure teams each see only their part.

06

Compliance exists on paper

Policies exist, but nobody has verified whether the systems actually implement them.

Then you don't need another developer first.You need someone who understands the system.
02 — SERVICES

05 — METHOD

Understand first. Change second.

No black-box consulting. I combine architecture-level thinking with the ability to inspect the technical detail myself.

  1. DiscoverWhat actually exists?
  2. UnderstandHow does it really connect?
  3. AssessWhat is critical?
  4. StabilizeWhat should happen first?
  5. ControlHow do we keep visibility?
