Hello, I'm Eduardo — a backend engineer with 4 years of experience building distributed, event-driven systems in Java and Kotlin. These days I keep a high-throughput platform fast and reliable at Blip.
(01)Who I am
What keeps me hooked on this work is the moment a hard problem finally gives in — when the pieces click and a system you've been wrestling with finally starts to work.
I studied Informatics Engineering in Porto and haven't stopped building since. Most of my time now goes into backend work — distributed, event-driven systems in Java and Kotlin — keeping a high-throughput platform fast, observable, and hard to knock over.
My daily tools: Spring Boot, Quarkus, Kafka, and Flink, running on AWS and Kubernetes (3× AWS certified). I still ship the occasional front-end with React, and lately I've been having fun building AI agents in Java. Got an interesting backend problem? I'd love to hear about it.

(05)Career
Sep 2024 - Present
Porto, Portugal 🇵🇹@Blip.pt
I build the backend of a high-throughput betting platform — Java 21, Spring Boot, Kafka, and Apache Flink on AWS and Kubernetes. Along the way I shipped a production AI chatbot with Spring AI on Bedrock, led the move to structured logging with Grafana dashboards for the on-call team, and made disaster recovery a lot less scary with automated Flink savepoints.
