CV Alexander Strasser

gästeliste.club is a highly specialized SaaS for clubs and discos. Built with Next.js, Tailwind CSS and Headless UI, it enables clubs to not only have a single source of truth for their guest management, but also provide an easily usable interface for their security workforce, cashiers and promoters.

This idea came from a friend of mine working in event business - traditionally, most clubs manage their guests using Excel spreadsheets and sending them back and forth.
The requirements included minimal data usage and power drain of mobile devices, rights management for the various users and live statistics about people entering the location.

Under the hood it utilizes fuzzy-searching to allow finding guests in seconds even when not spelled correctly, and a hash-based cache-invalidation scheme to minimize loading times, data utilization and battery drain for security employees working outside.

Customers can also show reports of their guest arrivals, share invite links for self-entry of guestlist places via social media and export their data to Excel files in seconds.

This project is already live and in usage for several months: Beta customers checked in nearly 5000 Guests at the gates of their locations, the individualized invite pages were clicked several thousand times by Instagram followers and my Express JS backend served over 200,000 requests.

Next steps include internationalization, finishing dark mode and smaller enhancements. On the roadmap are also ticketing services and ticket invalidation - customers can then sell tickets online and easily scan ticket QR-Code from either pdf or Apple/Google Wallet at entrance.

If you want to have a closer look at the application, just contact me and I'll send some credentials for the staging environment.
