Lead Software Engineer · .NET · TypeScript · Cloud
I got my first computer for Christmas when I was eight, and software has not let go of me since. Today I am a technical lead at Hoffmann Group, responsible for the architecture and direction of a small team. I learn fast, most recently how to work with AI agents, and people can rely on me.
Worked out the technical product vision and architecture with product owners and stakeholders. Then built the first release for Hoffmann customers with the team, spec-driven and with AI agents in the process.
Ran customer interviews together with the product owner and evaluated the feedback with AI. That produced the first concepts, the foundation of the technical product vision.
Built new features together with the stakeholders and modernised existing code. This included integrating a browser application for assembling complete tools graphically.
Developed a backend-for-frontend microservice that exposes simplified REST endpoints. This made it considerably easier for another team to connect the HCT Connect app.
Integrated a SAST tool and automated dependency checks into the CI/CD pipeline. This added further steps to the secure software development lifecycle of Password Safe.
Implemented a SCIM 2.0 endpoint for Password Safe, test-driven. It lets customers provision users and groups straight from their identity provider, such as Azure AD or Okta.
Designed the successor to EurOwiG Ordnungswidrigkeiten and tested it in the first proofs of concept. The result: a multi-tenant Angular SPA with a backend on .NET Core.
Designed, built and published a native iOS app with Xamarin. Authorities and external service providers use it to record parking violations directly while on patrol.
Designed, built and ran a multi-tenant SaaS platform. Recipients of a hearing notice fill in their hearing form there and submit it online.
Built and ran a web app for municipal enforcement staff on smartphones and tablets. Alongside it, the multi-tenant web service that connects field and office staff.
Designed and built a modular online configurator for putting together craft services. Implemented with C# and ASP.NET, in the browser with jQuery and Ajax.
Extended and optimised the in-house ReadyWeb CMS that hotels used to maintain their websites. This included further development of the booking interface for online room reservations.
Completed the apprenticeship as an IT specialist for application development with an overall grade of “good”. The foundation was object-oriented programming, at the company and at vocational school.
Developed and supported the in-house product e:maxx Schüttgut in Delphi. Large plants use it to weigh their trucks loaded with bulk material.
I orchestrate AI agents and build the processes in which they deliver reliably: clear specs, rules per project and pull requests that have to pass typecheck, linter and tests first.
I lead technically, with a clear direction and plenty of trust. I use code reviews, pairing and open feedback so that the team grows and takes on responsibility itself.
I translate between engineering, product owners and management. I explain complex technology clearly, make decisions transparent and settle expectations early.
Software should not just work, it should stay maintainable. Clean code, a well-considered architecture and automated tests take care of that and make every release safe.
I break large undertakings into realistic stages with clear milestones. I raise risks early, so that schedule and resources stay predictable even in critical phases.
Good software is built as a team, on a basis of trust and respect. I share knowledge openly, solve problems together and deliberately bring different perspectives to the table.
What I mostly work with, by area. The bar shows how deep I am in each.
Three projects built alongside my job, all 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.
CV, applications and photos in one app
This website, replacing a Vercel app and a WordPress blog. Every application gets its own link to the cover letter and references, managed in an admin of its own.
When I am not at the computer, I am out on my motorbike or outdoors with the camera. My favourite subjects are macro and wildlife, and a selection of them is right here.
Feel free to reach out to me via email or connect with me on social media.
