Mentoring

Personal guidance to grow faster as a developer.

As a developer, you're good at your craft.

  • You break down larger problems into smaller, logical steps.
  • You test your code automatically.
  • You write code that others can easily understand and build on.
  • You already think beyond the immediate solution — architecture, maintainability, scalability.
  • Other developers regularly ask you for advice or your opinion.

But you still face a number of challenges.

  • You sometimes have trouble saying "no" or setting boundaries when a deadline is unrealistic.
  • You notice that being technically strong doesn't automatically lead to more influence or recognition.
  • You know you can make more impact, but the path to get there isn't clear.
  • You don't always communicate as effectively as you'd like with non-technical colleagues or stakeholders.
  • You feel there's a next step in your career waiting for you, but you're not sure exactly how to take it.

Sound familiar?

Technical excellence alone won't get you there. The developers who truly grow have someone who takes them further than they'd ever get on their own.

What you'd figure out on your own in 5 years can happen in 6 months with the right guidance. I help you grow in all aspects of the job: development, architecture, processes, communication, priorities, customer interaction, efficiency.

Personal 1-on-1 mentoring for developers who want to grow faster.

What I do

I guide developers 1-on-1 to grow faster and more purposefully, in all facets of the profession.

How it works:

Kickoff session of 3-4 hours

Together we set clear goals: where do you want to go and what do you need to get there?

Weekly online sessions of 1-2 hours

Regular contact for progress, feedback, and concrete action items

Program of 3, 6, or 12 months

Depending on your goals, we choose the right duration

All aspects of the profession

Development, architecture, processes, communication, priorities, customer interaction, efficiency — everything is covered

The result: faster growth, more confidence, and greater impact.

When I'm typically engaged

You want to grow into a senior or lead role and want to work toward that purposefully

You just started in a new position and want to be effective quickly

You notice you're technically strong but struggle with communication or stakeholder management

You want to make more impact within your team or organization but don't know where to start

You feel stuck in your development and are looking for an experienced sparring partner

About me

With more than 25 years of experience in software development, architecture, and leadership, I've seen what works and what doesn't. I help developers take the steps I had to learn myself — but without the detours.

Looking for group-based guidance? Check out group mentoring — weekly sessions with other developers, starting September 2026.
