For me, software development is both, a craft and a passion: I have been learning all I can about
programming languages, paradigms and adjacent technologies since I was 12 years old. I have made
software development my profession starting 2013.
As such, I am a competent and seasoned PHP (Symfony / Laravel), Golang
and TypeScript / JavaScript developer that doesn't just implement the logic but ensures
that the project is scalable and maintainable in the future.
DevOps
Running Linux on all kinds of devices, starting at Workstations and Linux but also including
Phones, Microcontrollers, Single Board Computers, Routers has always been a hobby of mine.
This makes me a passionate DevOps Engineer with practical knowledge about Linux, in both
more traditional setups using tools like Ansible or Chef and more
advanced setups using Docker, Kubernetes and CI/CD Pipelines.
I will help modernize and streamline your software development workflow and infrastructure management to
ensure maximum productivity of developers and high availability of your applications.
Projects
Powderguide Conditions Reports
2024 - 2025
Modernization of both the mobile app and the corresponding backend system for the PowderGuide Conditions Reports.
The app is used by ski and snowboard enthusiasts to report snow conditions and avalanche danger.
The backend of the application was moved from a mix of a legacy Laravel version and TYPO3 to a modern
Laravel version, embedded in (but still architecturally separated from) the Statamic based website.
This included porting the TYPO3-based login logic while preserving the existing password hashes to
allow a seamless transition for existing users. The mobile app was rebuilt using React and Typescript
and ported to a modern version of Ionic.
Biallo Website
2024
Migration of the Biallo website from a legacy in-house system to a Neos-based website, including a large
backlog of existing articles and pages. The migration was done using a scraper-based importer, as the
database of the legacy system was not easily accessible.
Powderguide Website
2023 - 2024
Migration of the Powderguide website from a TYPO3-based system into a Statamic based site. This included
the migration of multiple thousands of articles from the old system into the new system using a custom
importer to convert the data into the bard format used by Statamic.

2022 – 2025
