Educational networks with dozens, or hundreds, of units operate around a quiet but expensive problem: how to make sure every school, every administrator, and every local manager has fast, organized, standardized access to the brand's marketing assets, while still allowing the customizations that local reality demands. COC, one of Brazil's largest school networks, came to us with exactly that pain. Campaigns had to be distributed quickly across partner and licensed schools, with distinct visibility rules, granular access control, and an organized flow for customization requests. All without losing the governance that an operation at this scale requires.

The hard part wasn't the asset library. It was building one system that could hold two opposite forces at the same time: brand consistency at the national level, and operational autonomy at the local one. Every shortcut in either direction would break the other. A static asset library would frustrate local managers who needed customizations. An open customization tool would erode the brand within a quarter. The portal had to be both at once, with the governance layer to keep it that way. On top of that, the portal had to live inside an ecosystem that already existed (the COC identity layer, the network's school database, a list of partners and licensees with different rules), and had to feel like a native extension of that ecosystem, not a new system schools needed to learn.

We built the COC Marketing Portal as a custom web platform that centralizes marketing-asset distribution, customization requests, and the administrative control of the entire network's communication operation. The application is built in PHP with Laravel, backed by MySQL, hosted on AWS with S3 buckets for asset storage, and fully dockerized. Authentication is integrated with Passaporte COC, the network's single sign-on system, so users from the schools don't need new credentials. A recurring sync with the COC API keeps the partner-vs-licensee classification of every unit up to date automatically, so the portal always knows who's supposed to see what.Around that core, the platform layers in granular access control, a structured customization workflow, an external-asset validation flow for agencies, strategic reporting, and full LGPD compliance.
