About Nuno

I am an IT contractor (B2B | Remote) with more than 20 years of experience designing and delivering distributed backend systems for international companies across a wide range of industries.
My core expertise is centered around Java and Kotlin backend development, microservices architectures, cloud-native platforms, event-driven systems, and high-availability services.

Throughout my career, I have lived and worked internationally with teams across Portugal, the Netherlands, the United Kingdom and Spain.
I am particularly comfortable in remote-first environments and asynchronous collaboration models. Having worked with globally distributed teams for many years, I value clear technical communication, ownership, autonomy, and pragmatic delivery.

In addition to my technical skills, I have worked in various organizational setups, from startups to large enterprises, adapting my approach to each unique project and team. This exposure has equipped me with the versatility to thrive in dynamic environments and manage complex technical challenges efficiently.
