Understanding complexity.
Creating structure.
Building momentum.
My career doesn't fit one clean lane. I'm a German-American based in Berlin, and my path has taken me from biochemistry into product, operations, and organizational leadership — at times serving as a de facto chief of staff alongside more traditional product and operational responsibilities. Over the years, I've helped build products, redesign processes, scale teams, and introduce new systems in environments ranging from early-stage startups to Fortune 200 organizations.
What connects those experiences is a fascination with how people, processes, and technology interact. I'm most energized by situations where there isn't a clear playbook yet — where progress depends on understanding the problem, aligning stakeholders around a shared goal, and building practical solutions that deliver meaningful results. Whether the challenge is a product, a process, a team, or an organizational system, I'm interested in helping people work more effectively and creating structures that can adapt, improve, and scale over time.
How I Work
That means talking to customers, observing workflows, reviewing available data, and spending time with the people closest to the problem. The goal isn't to collect opinions — it's to understand reality before deciding what should change.
This often means surfacing tradeoffs, challenging assumptions, and helping stakeholders agree on what matters most. Complex problems become much easier to solve when everyone is working from the same understanding and shared goals.
Whether the answer is a product, a process change, a new system, or a workflow redesign, execution is where ideas meet reality. Technology can be a powerful enabler, but it's not always the right answer. I'm more interested in achieving the outcome than implementing technology for its own sake.
Once something works, the next challenge is making it sustainable and continuously improving it. That means refining products, systems, processes, and team ways of working while balancing attention to detail with a broader systems view.
