Experience

Aiacta - Virtual Tabletop Simulator

A TypeScript-based web application to enable remote tabletop games. I developed this application to experiment with different approaches and to try new technologies on a bigger project.

I explored a peer-to-peer application design with minimal server requirements.

Currently, I'm re-developing this app using React, GraphQL, Prisma, Node.js, and various small frameworks.

Billigflieger

A React, Kubernetes, and Node.js-based web application for searching and comparing flights. I was the senior front-end engineer tasked with migrating the old platform from Embedded JavaScript templates (EJS) to a modern React application. I built and maintained the CI/CD workflows and implemented SEO-optimized server-side rendering before there were big frameworks and libraries.
