Virtual Scroll for Tree-like Structures
Work Done:
• Created a custom virtual scroll solution for data structures that are not flat but hierarchical.
• Improved page loading times by up to 25 seconds.
• Added the possibility to dynamically extend and collapse data within the hierarchical structure, as that is likely to happen with this kind of data structure. (On large amounts of data, the page wouldn't load without the virtual scroll component.)

Mortgage Request Platform | Fintech
http://swissfex.chA mortgage-management platform based on Angular and .NET Core for one of the leading insurance firms in Switzerland. The platform allowed mortgage advisors to get their clients through the process, from creating the dossier until finalizing the mortgage contract and receiving financing.
I was a part of a two-person development sub-team responsible for the client-facing front end. Besides the Angular web app, our responsibilities included a proxy server with the main API and a couple of third-party integrations.
