Top SchoolGustavo Fonseca is a Senior Software Engineer with six years of experience building scalable, resilient distributed systems and high-performance monoliths, currently shaping core services at Sicoob. He combines deep backend expertise in Java, Spring (including WebFlux), Kafka and Kubernetes/OpenShift with hands-on experience in cloud-hybrid deployments (AWS & on-prem) and observability tools like OpenTelemetry, Grafana and the ELK stack. His work spans the full delivery lifecycle—from domain-driven design and UML-based architecture to incident response and performance refactors on production-critical financial systems, including Open Banking/Open Finance standardization. Beyond enterprise systems, he has engineered IoT and embedded solutions with ESP32/Arduino, MQTT brokers and TinyML research for embedding reinforcement-learning models on microcontrollers, reflecting a strong blend of systems and edge-level thinking. Comfortable leading squads and mentoring engineers, he is equally at home authoring production services and contributing to open-source research and hardware-aware software.
