I help teams build software that drives your business

I connect business needs with technical decisions and give teams the clarity and space to deliver. I bring practical experience across architecture, development, and running products. AI is one of the tools I use.

Selected work

Products I own, systems I have helped build, and teams I have helped move forward.

Product creator and operator

Mira Checks

I created and operate Mira Checks, a SaaS product that checks whether business-critical forms, bookings, checkouts, and other website journeys still work after a change.

I am responsible for the product, architecture, development, self-hosted AI infrastructure, hosting, marketing, sales, support, and daily operation. It is the clearest example of how I work: understand the problem, build the system, and remain responsible after launch.

Agricultural marketplace

Raiffeisen

I helped build akoro, a shared digital platform connecting agricultural businesses with Raiffeisen cooperatives across Germany.

Internal publishing platform

Mercedes-Benz

I worked on an internal platform for managing documents and digital publications.

Delivery leadership

Volkswagen Commercial Vehicles

I stepped in to rebuild trust between the development team and client stakeholders. I made technical progress visible, negotiated priorities, and involved stakeholders in resolving blockers.

What I do

I work with stakeholders and developers to understand the problem, set technical direction, and make trade-offs explicit. I listen to how people work before proposing changes.

I am most useful when the problem crosses boundaries. Product, software, systems, people, and operation rarely fit into separate boxes.

Decide

I clarify the problem, constraints, risks, and cost before choosing a solution.

Build and improve

I build new products and repair systems that have become slow, fragile, or difficult to change. I prefer a focused change over a rewrite when it solves the real problem.

Lead delivery

I establish priorities with the team and leave room for them to decide how to deliver. I protect their focus, remove obstacles, and make time for improvements that matter.

How I work

I am a problem solver and a pragmatist, not a tech-stack follower. I make complex decisions understandable. I choose the simplest setup that helps the business.

I use AI every day for development, testing, research, and automation. I also know its limits. Faster output only helps when it is useful. More is not automatically better. The goal is to help, not overwhelm.

I stay close to the code. Diving deep into the implementation gives me the confidence to own decisions and the clarity to be transparent with stakeholders.

Open source and workshops

Open source

QAgent

I built QAgent to test AI-generated software against real user goals in the browser. A driver model performs the task. A separate model judges the result. The separation makes the test harder to bend just to produce a pass.

Workshop, Vibe Coding Bremen, IJCAI Special 2026

Spec-Driven Development

I taught a sold-out practical workshop on using specifications to keep AI-assisted development deliberate, testable, and understandable.
