Marcelo Del Fiore

I’m a backend software engineer with over 30 years of experience, originally rooted in electronics and later focused on backend development using Ruby on Rails, Python, and Elixir. Over the past seven years, I’ve built robust, scalable web applications and APIs, specializing in complex systems and large codebases while staying passionate about clean code, automated testing, and data-driven applications.

I thrive on business-critical work—building data pipelines, IoT systems, and event-driven architectures with tools like RabbitMQ and Kafka. I’ve led migrations (e.g., moving a React frontend to Phoenix LiveView to reduce technical debt), shipped APIs across gRPC/GraphQL/REST, and delivered measurable outcomes such as improving forecast accuracy by 3%, increasing client base by 6%, and contributing to an 11% increase via a PIX microservice. I also bring leadership experience from managing multidisciplinary teams building SCADA systems, taking projects end-to-end from embedded design to real-time software.
