The problem
Scheduling, commission, subscriptions, and reminders were fragmented. The shops needed a multi-tenant system that digitized the day without a heavy operation.
What I did
I built scheduling, staff payroll, a subscription engine, and automated reminders with Next.js, Node.js, Prisma, AWS S3, Resend, and Vercel. The other projects ran from Figma through production.
What holds the case up
- 01
Product scale
7,000+ registered users.
- 02
Time in the operation
Clients saved about 17–20% of daily operational time.
- 03
B2B delivery
40+ complete projects: systems, landing pages, automations, and BI.
