Marcelo Lima

I’m a seasoned Technical Lead and Software Architect with 20+ years in IT, currently specializing in high-performance fintech and banking solutions. I focus on building and evolving systems that deliver critical outcomes with reliability, including zero-downtime deployments and high availability.

I’m an expert in the Java ecosystem (up to Java 21), microservices, and cloud-native architecture. In my current role, I lead migrations and development using Java 21 and Quarkus, improving startup time and resource efficiency compared to legacy stacks.

I also architect event-driven solutions with Apache Kafka for real-time transaction processing and consistency across distributed systems. I guide full-stack integration by connecting robust backend APIs with modern frontend experiences built on Next.js and React.

I’m passionate about AI, code quality, and mentoring developers. I’ve explored AI-driven tools to optimize engineering workflows and enhance product features, and I bring strong practices in Domain-Driven Design (DDD), CI/CD, and agile delivery to every team I lead.
