Summary
Over 9 years of full stack experience (C#, .NETStorybook, Vue.js, React) with a focus on modular architectures and scalable portals. Many years of experience applying Clean Architecture, CI/CD, and Domain-driven Design. Industry focus: energy, public transport, construction. Tech Lead in 5+ projects.
I work in a solution-oriented and structured way, with high standards for quality, without taking unnecessary detours, but always keeping the bigger picture in mind. It is especially important to me that technical solutions not only work, but also genuinely simplify processes and run reliably.
I take an active role, think outside the box, and speak openly about issues when they hinder the progress of a project. I work with specialist departments and project partners in a clear, reliable, and equal partnership.
What drives me is the goal of making complex topics easy to understand and turning good ideas into stable, practical systems, without unnecessary complexity but with maximum value.
