Carpe Diem

The client, Carpe Diem, is a spinning studio company in Mexico, and they needed an admin and user interface.
In the admin interface, they keep track of their business and register weekly classes. They have the capacity to add, edit, and remove the instructors, register new users and their payments, and get business analytics data on the company.
In the user interface, new clients can register, see the classes and the instructors, buy credits, monthly subscriptions, book classes, get email notifications, and see their purchase history. It was implemented with Stripe's API.
I implemented the front end, back end, system design, database structure, and cloud deployment.

Dan Cassab

Dan Cassab is a premium clothing company with worldwide customers, and they wanted to improve their eCommerce from a Shopify template to a custom website. I followed their custom design using Angular for the front end and connecting the Shopify back end with a GraphQL API. The inventory and the checkouts are managed by Shopify.


Shopify store with template customization.
I created new pages following the design provided by the team, the pages were built using liquid and the Shopify building blocks to facilitate future modifications by the client form the theme customizer.
I used a theme kit to download the source code and keep a GitHub repository for version control and code backup.
Some products required custom pages to select special options not fulfilled by the varients, like suit cut and button pattern, this was implemented by modifying the product form to add properties, and using meta fields to show additional information.
