The problem
Paula sold courses, tinctures and sessions by message: she tracked by hand who had paid, who was coming to each session and what was left in stock.
What I built
A site with her own identity where customers buy or sign up on their own and pay with Mercado Pago, plus a panel where she sees payments, orders and attendees.
Store with cart
Physical products, recorded courses and sessions, with stock control and photos optimized on upload.
Sign-ups with seats
Each session, in person or online, shows the seats left and closes when full.
Session bundles
Several sessions in one payment, offered only while at least two are still ahead.
Mercado Pago checkout
The client’s own account, linked with OAuth; every payment is confirmed by a signed, verified notification.
Admin panel
Payments, products, in-person and online courses, attendees and orders, with its own users.
Data sheet
A record of people and the courses each one took, filled from the site or by hand.
Both sides
What customers see, and what Paula sees
How it’s built
- Runs on the same server as Alhia, separated by domain: the site takes payments without extra infrastructure.
- Mercado Pago payment notifications are rejected unless they carry a valid signature.
- Forms protected against abuse: rate limits, a honeypot field and automated submissions discarded.
- Images compressed on the server and served from cloud storage.
My role
Built the store, sign-ups, payments and admin panel; deployment and ongoing maintenance.
