Vinícius Ferreira

I’m a backend engineer specializing in Java and Spring Boot, focused on building scalable, high-performance systems that process large volumes of data. I design backend solutions that integrate multiple platforms and automate complex business workflows while keeping reliability, scalability, and security at the center.

My work has emphasized production readiness and performance: I reduced page response times by up to 80% using Redis and advanced caching strategies. I’ve also designed scalable backend services supporting an estimated 10,000 concurrent users, with clear system design and maintainability as core goals.

I build event-driven, integration-heavy workflows as well. I’ve implemented webhook-driven integrations connecting Facebook Lead Ads, Pipedrive, and Zapier to automate customer acquisition pipelines, and I integrated Stripe payment processing for subscription management while contributing to more than €10,000 in generated revenue.

I’m equally focused on operational excellence. I implemented observability using Grafana to monitor application performance and system health, and I apply SOLID principles, Clean Architecture, and Domain-Driven Design to keep systems maintainable and production-ready as they evolve.
