Helping the teams with their frontend libraries, a unified component library, and transitioning old external solutions into modern internal projects.

I first supported the software company building an entirely new frontend experience for their customer portal with the latest technologies but also integrating legacy APIs and various internal services. After the architecture and base was in place, I changed teams and helped the company’s explorative team to get more effective. We worked on AI solutions for customers to help them understand their reports and alerts better and plan ahead of time. The team also builds various (realtime and on-request) APIs out of the generic datapool (orchestration) and has to serve efficiently millions of messages, alerts and other data to customers in realtime. During my time there, the team got more stable despite member changes, more effective and learned to work on the really valuable things for our customers. I introduced proper but lean workflows that serve better than Scrum out-of-the-box, held workshops, introduced End-to-End Testing, performance checks and a variety of factors that lead to a better product while the team can work in a calm mode. This was highly appreciated and acknowledged by the team and its managers.

I got hired by the frontend team at Siedle to get one of their refactoring projects up to speed and fix it in a short amount of time. This meant replacing dozens of web components with a modern Angular stack, rebuilding the entire CSS stack from a bloated one to a lean and effective codebase. In the end, we gained performance benefits in the frontend that reduced rendering by a few seconds to now "not noticeable" despite the product being a very complex data platform with a lot of dynamic options and data load mechanisms. During my time there, I also coached the on-site team about the modern front-end stack and how to build efficient and fast web apps with their chosen technology and fixed a couple of legacy problems while at it. The team would really have loved to continue working with me but the project had a fixed end and I was booked by another company right away.
