Summary
Hey! I'm Jonas and I'm a freelance Product Owner for web, API, backend, and app development teams.
I work best in a team with talented designers and developers. I act as a multiplier who ensures that each person has all the information they need and can work at their best. My technical-analytical skills lead to well-thought-out concepts and efficient refinements. With my understanding of both worlds, I build a bridge between business and IT.
I am a system integrator. I have a quick grasp. By asking questions, reading documents and software source code, and creating various diagrams, I build a deep understanding of the existing or to-be-built system. In my past as a developer and software architect, I have learned various system designs and technologies, so I can quickly find my way in a new system landscape.
I am a translator. I don't just translate needs into requirements and requirements into software, I also translate between the people and teams in the company. I understand business as well as IT, and I build a bridge between both worlds.
I am a moderator. With my deep understanding of the system and the issues to be solved, I quickly recognize when people are talking past each other and help drive meetings forward productively.
I am a multiplier. In all past projects, I was the go-to person for the business units, designers, and developers. I advise adjacent business units and other stakeholders on finding the most effective solution. I help designers by making technical possibilities and constraints transparent so they are informed of all boundaries. I also give constructive feedback—supported by evidence from studies or past experiences. Developers come to me to clarify functional aspects, but also to get pointers on the overall system functionality or the best contact person. Often, I am shown software source code because developers know I understand it.
I am a trainer. I don't hoard the knowledge I've gained; I pass it on. In every project, there always comes a point where I share knowledge about the product, the technical systems, or a technology in the form of training sessions.
I am an architect. Backed by my understanding of the overall system, I create well-thought-out concepts for implementing the required or desired functionality. I try to consider all possible edge cases and error cases so that potential complexities are identified or made transparent early. I get all parties on board early so there are no surprises.
I am a quality assurer. Quality is especially important to me. I don't like bad software. That's why I make sure there is a working quality management process in the team.
