Cadu
// Full Stack Developer
Building scalable applications with React, Node.js and TypeScript since 2019. Focused on performance, security and clean code.
// About Me
Full Stack Developer focused on backend and DevOps, turning complex systems into scalable, secure architectures with costs under control.
Hi, my name is Carlos Eduardo, but you can call me Cadu. I work as a Full Stack Developer at Going2 Corporation, where I'm also a team leader and product engineer. I led the rebuild of an educational management system serving nearly 2 million students across multiple states.
My background spans diverse products: a sports video streaming platform with native payments, a financial ERP integrated with Bradesco bank, a delivery app with Stripe Connect payment split, and an analytics platform for Mercado Livre. On the infrastructure side, I deploy CI/CD with Terraform e GCP, built a security workflow with SAST analysis, implemented observability with OpenTelemetry, and reduced cloud costs through storage optimization, autoscaling, and resource management.
My principle is to build scalable, secure, high-performance systems — clean, testable code that's easy to evolve, always applying software engineering best practices.

// Projects
A selection of the projects I'm most proud of.
SAEV
Educational management system focused on large-scale reporting, serving nearly 2 million students across multiple states. I worked across frontend, backend, and DevOps — optimizing infrastructure and storage and reducing cloud operational costs.
Wenner
Sports video streaming platform. I led the development team, optimized HLS video playback, integrated native Apple Pay and Google Pay payments, and built messaging with Cloud Pub/Sub for scale.
Financial ERP
Financial ERP integrated with Bradesco bank for automatic reconciliation and balance queries, with an event-driven architecture for auditable financial calculations.
PARC
Educational scholarship management system used by multiple states, with a flexible architecture that lets each state define its own workflows and granting rules.
Bodyfood
Vegan food delivery app (iFood-like model). I developed web, mobile, and backend, leading the payment split between restaurants and platform using Stripe Connect.
Himmelcorp
Analytics intelligence platform for Mercado Livre that transforms raw data into strategic insights on sales, pricing, and ad performance. I worked on the architecture and review of the GCP infrastructure: async pipeline with Cloud Tasks and Cloud Run, OAuth2 authentication with Redis caching, and operational/analytical database segregation.
