I started my career in IT support, moved into UI/UX design, and eventually found my place in frontend engineering. That path taught me to think about the whole product — not just the code. Over the years I've worked across university platforms, edtech, and now international event tech, each teaching me something different about scale, performance, and working with people.
I care a lot about writing clean, maintainable code and making things fast. I enjoy mentoring, owning the delivery cycle end-to-end, and bridging the gap between engineering and product. Outside of work, I write on Medium, build side projects, and slowly make my way through German lessons.
