## About

```text
At HipSquare GmbH, I partnered with an insurer’s leadership, an external consultancy, and the PM to define the frontend architecture for an Angular claims portal shell. It brings the claim lifecycle together while allowing 6–7 teams to ship Web Component micro-frontends independently.

I led frontend decisions within a team of five senior engineers, published a shared Angular modal library, and optimised the portal shell to a Lighthouse score of 100. I also covered it with Playwright end-to-end tests.

At inSparx GmbH, I helped extract the Angular frontend from a Spring Boot monolith and rewrite it as a standalone app with the frontend team. I also improved maintainability through an NgRx and RxJS redesign, faster builds, and Jest unit testing.

Across my work, I’ve built payment and subscription flows, online registration, chat and video calling, and web experiences for enterprise and consumer products. I started as a freelance web developer, delivering e-shops and websites for local businesses.
