Cirene
A multi-tenant platform where merchants run coupon campaigns, affiliates earn per sale through a running current account, and a commercial rep hierarchy is paid on its own quota structure. Rebuilt from a legacy Oracle APEX system that never reached production.

Dra. Rebeca Soares Andrade
A physician’s content and business platform: health articles, a press room, gated streaming with subscriptions, supplier and service-provider pipelines, and a company consumption portal — published in ten languages through an LLM-assisted translation workflow built into the CMS.
