I'm Stefano Guerrini, a backend software engineer based in Haarlem, Netherlands.
I currently work at Marktplaats, where I help scale one of the biggest marketplaces in the country.
I work — and I've worked — with a bunch of backend technologies like Java, Scala, Kotlin, Kafka, Debezium, RabbitMQ, Redis, MySQL, Postgres, AWS, Docker, Kubernetes and more.
I love designing event-driven systems — clean, asynchronous, and built to scale.
I enjoy working in teams where collaboration, transparency, and shared ownership are part of the culture.
I like solving real-world problems with simple, scalable code.
