18 years building .NET and TypeScript systemsAugsburg region, Germany
... a great Christmas present 28 years ago: my first own computer. The performance of this 'marvel of technology' is currently probably surpassed by any better smartwatch, yet this PC was the cornerstone for my way into the digital world of today. With it I learned the basics of a text-based operating system, how to use a mouse and what this Minesweeper was all about.
Since then I am interested in everything that has to do with bits and bytes. The area doesn't matter, from A like Artificial Intelligence over M like Mobile Device Development up to Z like the ZIP algorithm.
Dream job: software engineer? For me it really is! Today, 21 years after the beginning of the training, I have a profound expertise in almost all areas of agile software development and in parts of DevSecOps. Today I am the technical lead of a small team, responsible for architecture and technical direction rather than for line management.
This know-how has been gained through the implementation and support of a large number of projects as well as my personal interest in realizing them with the help of the latest technologies.
An always concentrated and conscientious way of working and the ambition to continuously deliver optimal work results. I value solid communication as well as close cooperation within the team. In addition, my colleagues can rely on me at all times. What's more, I'm motivated, like to familiarize myself quickly with new projects and fields of activity, and am eager to develop professionally.
I was born 37 years ago in Augsburg, Germany. I successfully completed my traning as an IT specialist in the field of application development 18 years ago and have been working as a software developer in the field of web technologies ever since.
Besides my professional hobby I also like to spend my free time on the motorcycle or behind the camera. In the latter, I am particularly fond of macro and wildlife photography.
Technical product vision and architecture worked out with product owners and stakeholders, then the first draft of the system for Hoffmann customers. Development follows Spec Driven Development, with AI in the development process.
Customer interviews with the product owner, evaluation of the feedback with AI and from that the first concepts: the basis of the technical product vision.
Many new features were developed together with stakeholders and existing code was also newly developed/further developed in this context.
Integration of a browser application for the graphical assembly of a complete tool within Connected Manufacturing.
Development of a backend for frontend microservices (BFF) which publishes simplified REST endpoints and thereby simplifies the connection of the HCT Connect app by another team.
Integration of a SAST tool as well as an automated dependency check into our CI/CD pipeline for an even better Secure Software Development Livecycle (SSDLC).
Implementation of a SCIM 2.0 standardized endpoint in the Password Safe product to facilitate provisioning of users and groups from the customer's deployed Identity Provider (IDP) such as Azure Active Directory or Okta following the Test Driven Design pattern.
Conception and implementation of first proof of concepts for a software solution as successor for EurOwiG Ordnungswidrgkeiten. The result was a concept of a SPA based on the Angular framework with a backend system based on the .NET Core Framework.
Design, development, and operation of a multi-tenant platform for the collection of hearing forms by the hearing recipient.
Design, development and operation of a progressive web application for use in the mobile order service on smartphones and tablets for the rapid recording of messages in the field.
Design and development of a modular configurator in the field of craft services.
Completion of my apprenticeship as an IT specialist specializing in application development with an overall average of Good.
During this time, I learned the basic techniques of object-oriented programming through my instructor and the vocational school.
For me, teamwork is the fundamental element of excellent software development, based on mutual trust and respect.
I actively establish a culture of open knowledge exchange and collaborative problem solving through methods such as pair programming.
This approach not only strengthens team spirit, but also leads to high-quality solutions more efficiently through diverse perspectives.
For me, modern leadership means creating an inspiring environment in which innovation and individual excellence flourish.
I lead teams with a clear vision and empathy, fostering the personal development of each individual through constructive feedback and coaching.
My focus is on building psychological safety to form high-performance teams that deliver outstanding results on their own responsibility.
I consider targeted mentoring to be an essential investment in the sustainable development of the team and long-term knowledge transfer.
I actively accompany colleagues through code reviews and workshops to deepen technical understanding and firmly anchor best practices.
It is my personal aspiration to empower others to surpass themselves and take responsibility for their own career path.
Precise and target-group-oriented communication forms the backbone of successful projects and sustainable stakeholder relationships for me.
Through my experience in technical project management, I convey even complex issues in an understandable way between development and management.
I attach great importance to a transparent, solution-oriented dialogue in order to proactively avoid misunderstandings and clearly define shared visions.
My quality standard defines software that is not only functional, but also robust, scalable, and maintainable in the long term.
By using modern technologies and best practices such as Clean Code, I ensure sustainable architectures from the very beginning.
A comprehensive test strategy with automated procedures ensures this high standard and creates confidence in every release.
A structured and methodical approach is for me the indispensable basis for the timely realization of complex projects.
Through detailed analyses and realistic milestone planning, I always maintain control over resources and schedules even in critical project phases.
Proactive risk management and transparent communication ensure predictable and smooth project success.
Since 2025 I no longer write most of the code myself; agents such as Claude Code write it. That moves my work to the front: requirements, architecture and rules have to be written down so that a session with no prior knowledge can work from them.
Every package gets its own documentation for the agent, with conventions, commands and the pitfalls it would otherwise repeat. What it delivers arrives as a pull request and has to pass typecheck, linter and tests before I read it.
The result is measurable: PuckHub with four frontends and an API in about 25 person-days, a website including its CMS in five. Both are shown further down under projects.
Through years of working on a wide variety of projects, I have taught myself numerous technologies and used them successfully. The following graphs show the technologies I have worked with most extensively.
Two projects built alongside my job, both with Claude Code. They show how I work with agentic coding.
Multi-tenant SaaS platform for ice hockey leagues
League operations for amateur ice hockey: seasons, rosters, game reports, standings and a website per league. The game recaps are written by a language model.
Website relaunch with a built-in CMS
New website for a forklift school in the Allgäu, replacing WordPress. Courses, copy, images and inquiries are maintained by the owner in a small CMS of its own.
