I built and launched a signup and invoicing app as the sole developer for Young Drivers Academy, a Dutch go-karting school. The app replaced manual registration records and gives staff a way to see who’s attending, which mechanics are needed, and what parts to bring. It has around 50 active users across four account types: parents, drivers, mechanics, and administrators.
Event signups feed into an invoice creation and approval workflow. The app generates invoice PDFs, stores them in Google Drive, and sends app emails through Resend. I built the app with TypeScript, Next.js, and Prisma, and set up a GitHub Actions deployment pipeline for development, test, and live environments.
