So far I have developed various frontend and backend systems. Administrative tasks for websites, contacts, products, or advertising materials as well as analytical monitoring (production/medical measuring device data) and statistical presentation were the main focus. I gained experience working with large datasets. Performance analysis and optimizations were part of my responsibilities.
AI is a supportive assistant in development and speeds up my work by integrating into my IDE.
My focus and interest is programming. Naturally, the latest developments are the most interesting to me, e.g. everything around using Signals in Angular 18 or runes in Svelte 5.
