I’m a Data Platform Engineer based in Lisbon, Portugal.
Big Data & Infrastructure

Data Platform Engineer with vast experience in distributed systems. I have designed and implemented novel algorithms for data storage and replication systems across diverse environments. Currently, my focus is on Big Data tooling and infrastructure, managing clusters and data systems in both on-premises and GCP environments.
My skills include:
Previously, I conducted PhD research on distributed systems at NOVA LINCS, focusing on data consistency models and optimized replication strategies for location-aware data. I also worked as a Junior Consultant at SolidNetworks, developing distributed system software and engineering systems to efficiently replicate and manage large volumes of read-only data across high-throughput networks.
In my free time, you will find me enjoying one of my favourite activities: mountain biking throughout the countryside, stopping for scenic photography, listening and playing music, reading, and cooking.

Welcome to my photography section! As a hobbyist photographer, I love capturing the beauty of the world around me through my camera lens. My interests lie in outdoor and urban photography, with a particular fascination for plant life and natural scenery. I enjoy exploring different landscapes and capturing the unique details that make them special. Through my photography, I aim to share my love for the world’s natural and man-made wonders with others. You can find some of my works on my Unsplash page, where they are available to download for free.
