I help businesses and web agencies with new websites, web applications and further development of existing solutions. With 25 years of web development experience, I can take on projects independently or join your team when you need extra development capacity.
My tasks range from new web applications to getting more out of systems that are already running, always with a focus on performance, security and usability. I can take on the whole task or be the extra developer in a team, as extra capacity in your agency or as a permanent developer on your own solution.
New sites, further development and adjustments in Umbraco 7–17 – including webshops and headless.
From Umbraco 7 or 8 to a supported version – planned, tested and without surprises.
Flexible websites built in .NET and Umbraco, tailored to your business and easy to edit.
If your task doesn't fit one of the boxes, please ask. There's a good chance I can help.
I build new solutions and improve existing systems, from smaller, one-off assignments to long-term collaborations. Whatever the scope, I focus on understanding each client's needs and building solutions that work in practice.


Børne-Foto needed to modernize its online shop and internal systems without disrupting daily operations. I've updated the solution step by step, allowing old and new systems to work alongside each other. The new online shop is faster and easier to use, and online orders have increased by 35%.


Håndværkernøglen's website has been modernised and extended over the years with new features and integrations. I've migrated the platform from Umbraco 7 to 11, optimised key pages to achieve up to 100/100 in Google PageSpeed, and automated administrative tasks through integrations with the Danish company register, AI and self-service features.

A modern platform bringing together membership management, tournaments and online payments. I helped develop Backgammon.dk and have since expanded the platform with new membership features and integration of the DrawBoss tournament system.
I have worked with Jon for several years on updating and optimising our entire IT setup.
Jon has delivered not only technical solutions but also outstanding service, and his professional approach and ability to find tailor-made solutions have been decisive for our company's digital development.
Jon has played a decisive role in the development of our platform. With deep expertise in .NET, Umbraco and API integrations he has delivered a stable, scalable and intuitive solution.
His professional approach, fast deliveries and technical insight are absolutely top class!
We have used Saalbach Consult for some years, and whether it has been development projects, smaller adjustments or bug fixes, Jon is both fast and flexible. He has integrated new tools on our platform and developed a large part of the functionality we enjoy today.
Jon quickly grasps the scope of a task and can estimate time with a steady hand.

I've worked in web development for over 25 years, primarily with C# and .NET, and have many years of experience with Umbraco. I've worked on projects both large and small, and I'm used to getting familiar with existing solutions – including code written by other developers.
As an independent developer, I'm the person you talk to and the one doing the work. I value straightforward communication, clear agreements and solutions that aren't more complicated than they need to be.
Need help with a single task or extra development capacity over a longer period? I work directly with businesses and as a subcontractor for web agencies. I can take responsibility for individual projects or join your existing team.
I generally charge by the hour, but fixed-price arrangements are also possible for well-defined projects. I work primarily remotely, but I'm also available on-site when it makes sense.
Have a project in mind, need help with an existing solution or just have a question? Tell me a little about what you need, and we'll figure out how I can help. I usually reply within 24 hours on weekdays.
