Patrick Söllner
I am a Senior Frontend Engineer with 10+ years of professional experience in agile product development and consulting. My focus lies in modular software design, design systems, and component-driven architecture. I prioritize customer and user needs, always choosing the right tool for the job — be that with my personal favorite React, Vue, or custom solutions with Web Components. My expertise extends to UI testing and advocating for accessibility, ensuring inclusive and resilient experiences for all users. Driven by curiosity and a commitment to continuous learning and personal growth, I challenge assumptions, embrace diverse perspectives, and deliver meaningful, maintainable solutions.
