Business first, always
I don't just deliver to spec - I consult you on the best way forward. Your business knowledge, my technical expertise — combined as we iteratively develop a better product than either of us would alone.
You don't hire me to build a dashboard or train an AI model. You hire me to know what you should do on Monday.
Your entire data team — in one person
With 12+ years across the full data lifecycle — as Data Engineer, Data Scientist, and Analyst — I design, develop, analyse and support your data solutions end-to-end.
No team to coordinate. No agency overhead paying for a junior to learn on your bill.
Honesty and integrity
My main motivation is creating real value. If I'm not the right fit or your goals can be reached with simpler means, I will not take on your project.
No rockets if you need a bike
The field is obsessed with the 1% cutting-edge and hides behind terms like "best-practice" and "frameworks".
I go beyond the hype and give you the solution that actually fits your needs and budget.
Professional engineering
My solutions don't break when your data changes.
They're secure by design, cost-effective and easy for another professional to pick up if needed.
Tested, not just delivered
In data, the worst errors go unnoticed.
Others skip testing to look cheaper. I test so you can trust the numbers.

Lars has been an outstanding contributor to the platform. He is extremely professional, communicates with clarity, and brings a strong, pragmatic, common-sense approach to everything he does. He has taken many of our early-stage ideas and turned them into practical, working solutions, several of which we originally thought were two to three years away from being achievable. Lars not only transformed these ideas into reality but delivered them within incredibly tight timescales, without compromising on quality. His ability to focus on what truly matters, make sensible trade-offs, and move quickly enabled us to deliver far more in a short period than we thought possible. Lars consistently took a pragmatic view that aligned perfectly with our delivery goals.
Lars is a thoroughbred professional. We had a great time collaborating. Right after starting the project, I realized that my idea needs more work. Lars was very accommodating and provided me with insights and recommendations that really took my project to newer heights. Lars has a deep understanding of the subject and is patient as a rock. And a combination of these qualities is a recipe for a SUPER collaboration.
What sets Lars apart is his ability to quickly understand both the technical side of a problem and the real-world business context behind it. He doesn't just build to spec, he takes the time to truly understand how your data behaves and how your operation actually runs.
Lars helped our team build a Data and Reporting Platform that completely transformed how we track and understand our business performance. We can now clearly monitor key metrics such as patient conversion rates, retention rates, and overall operational scorecards in a way that is intuitive and easy to interpret.
Lars is extremely responsive, easy to work with, and consistently delivers high-quality solutions. He does a great job translating operational needs into clear, practical analytics that help teams quickly understand their data and make better decisions. If something needs adjustment, he addresses it immediately and always communicates realistic timelines.
Lars was exceptionally good at understanding our needs and offering creative solutions using Python, Azure, and Power BI. He was consistently generous with his time and expertise, which resulted in a lot of development of my own skills throughout the project.
Do you need anything done with your data: this is the guy. Just a fantastic understanding about how the data flows and what you need as a customer.
What strikes me most about Lars is the way he makes the most advanced tech accessible to all. Not only through his amazing visualization of the data, but also through his communication throughout development. He can make very complex things simplified to see and understand, and this is a huge benefit not seen elsewhere. Truly worth every penny, as you get super sophisticated work, alongside a pleasurable and clear engagement. Can’t thank you enough!
Lars is an exceptional consultant. His expertise in data analysis and Power BI is outstanding, but what sets him apart is how deeply he understands client needs. He spent time with us to grasp our challenges, objectives and budget, and tailored his approach accordingly.
faq
maybe worth knowing
I am a bit unsure about my needs?
Perfect! This is where you get the absolutely most value from me. Let's have an initial chat about your needs - free of charge.
How should my initial brief look?
I strongly prefer plain, simple words directly from the heart :). Just focus on your business goals and we can work backwards.
Please don't use AI to generate your brief, as this will fill in a lot of assumptions that just acts as noise between us.
Why don't you provide specific work examples of code and solutions?
On principle, I don't share other clients' work and most of it is subject to IP rights and NDAs in any case. You can of course expect the same confidentiality in our work together.
How do you work?
I don't just deliver to spec - I consult you on the best way forward. Your business knowledge, my technical expertise — combined as we iteratively develop a better product than either of us would alone.
You don't hire me to build a dashboard or train an AI model. You hire me to know what you should do on Monday.
