Distributed systems

/ Porto, PT

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

About me

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 just starts to hum.

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.

My Experience

    Backend Developer

    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.
