Two ways to work together

Start focused.
Continue if useful.

The review process

Ten days from question to action.

The scope stays narrow enough to produce a useful answer, not a superficial tour of everything.

  1. 01

    Frame the decision

    Agree the question, boundaries, people, evidence, and success criteria before kickoff.

  2. 02

    Inspect the evidence

    Review selected architecture, code, telemetry, incident history, costs, and operating constraints.

  3. 03

    Test the options

    Make the trade-offs and assumptions visible. Identify what must be verified before committing.

  4. 04

    Make it executable

    Deliver the memo, priorities, owners, acceptance criteria, and a 30 / 60 / 90-day plan.

Fit

Who gets the most value.

Good fit

  • A working product or pilot
  • An important decision with a deadline
  • A technical lead who can provide evidence
  • A team able to implement the result

Needs a different scope

  • A full security penetration test
  • A compliance certification
  • A whole-company codebase audit
  • Day-to-day engineering management

Questions

A few straight answers.

What happens on the first call?

We spend 30 minutes on the product, decision, deadline, and fit. If I can help, I send a written scope and fee. The assessment itself starts after kickoff.

What access do you need?

Only what supports the agreed question: selected documents, code, diagrams, telemetry, or interviews. We agree access and handling before work begins.

Will you implement the recommendations?

Implementation is separate. Advisory can help your team review progress and make follow-on decisions within the monthly time budget.

Do you work with investors?

Yes, where the question is a focused technical or product risk assessment in energy or connected products. Broader diligence is scoped separately.
