Problem
Build a proprietary digital platform capable of combining useful tools, content, digital products, and a commercial marketplace in a single architecture while supporting SEO, monetization, scalability, and compute-intensive file processing.
Solution
A distributed architecture was built with Next.js for the public platform, Node.js/Express for processing services, MongoDB for persistence, Redis and BullMQ for asynchronous jobs, Cloudflare R2 for file storage, and Mercado Pago for purchases. The ecosystem also includes authors, payouts, promotions, analytics, notifications, and proprietary products.
