Case Study — 01
LinkTurno

Situation
Barbershops, salons, beauty studios and gyms still run their calendars over phone calls and messages. Every booking is manual, every reminder is someone remembering to send it, and a no-show costs a slot that was never going to be refilled.
Task
Build the product that replaces that, as the only developer on it — frontend, backend, infrastructure and database.
Action
- Designed the database schema and built the backend and API
- Built the frontend, from the booking calendar to the owner's dashboard
- Implemented authentication and account management
- Built the appointment booking and management flows
- Wrote a scheduled job that sends automated reminders
- Set up transactional email notifications
- Provisioned and maintained the infrastructure and deployment
Result
- A working SaaS in production, owned end to end by one engineer
- Every layer — schema, API, interface, infrastructure — designed to be extended without a team behind it
- Business owners can set themselves up and take bookings without help
