What we can work on

Feedback and hard conversations

Prepare a difficult talk, take criticism without getting defensive, and turn feedback into actual change.

Leading people in tech

New in a management role, a team conflict, or running a platform team between business and engineers.

Career change

Leaving corporate, a layoff, or a new direction. We sort out options, priorities and a realistic first step.

Personal coaching

Anything that's on your mind. You don't need to have it figured out before we meet.

Simpler household finances and Semi-FIRE

How I reached financial independence, shared as education. More about it below.

Five levels of receiving feedback

A model I built from years of watching people receive feedback, including myself. Most trainings stop at level 3. The change happens at level 4.

  1. No reactionThe least safe: nobody knows what landed.
  2. Explaining yourselfDefending the decision instead of hearing the point.
  3. CounterattackTurning the feedback back on the giver.
  4. Saying thank youPolite, and where most trainings stop.
  5. Asking what you could do differentlyThe only level that actually changes something.

Semi-FIRE: when work becomes a choice

Semi-FIRE means your investments cover a large part of your living costs, so work stops being a must. I got there over about five years of working on my own finances.

In sessions I share the method, not a product: how to see where the money goes, simplify accounts, set a goal with a date and stop worrying about every crown.

  • See your money clearly

    One simple overview of income, costs and savings instead of ten apps and a guilty feeling.

  • A goal with a date

    How much is enough for you, and when you could get there at your current pace.

  • Fewer products, less friction

    Look at insurance, pension savings and fees, and keep only what you actually need.

Education and mentoring only. I'm not a licensed financial advisor, I don't recommend specific investments and I sell no financial products.

How it works

  1. A short intro call

    30 minutes to see if we're a good fit. You check whether I'm the right person for you.

  2. Sessions of 60 minutes

    Usually around five, every two to three weeks. Google Meet, Teams or FaceTime.

  3. Your pace

    You choose the topic of each session. Everything stays confidential.

About me

I spent 11+ years at a global pharma company in Prague, growing from developer to Associate Director of IT platforms (DevOps, SRE, Agile).

The part of the job that gave me the most energy was people. For three years I coached colleagues internally, mostly on communication and feedback, two to four sessions a week. I've also spent four years in Toastmasters.

In 2026 my role was cut in a planned layoff wave. By then I had already reached Semi-FIRE, so instead of a shock it felt like an open door. Now I coach and mentor independently, and write on Substack about what I learn along the way.
