About

I'm a Software Engineer at Zalando Marketing Services, currently working on real-time bidding systems and bidding optimization problems.

From January 2019 to April 2021, I was a Software Engineer at Groupon, where I worked on the design and development of Java backend systems, based on REST microservices, to support connectivity with third party booking and ticketing partners. From August 2016 to December 2018, I was a Software Engineer at LeanXcale, where I worked on the design and development of a large scale distributed database, with focus on improving performance and scalability of analytical workloads.

I was also a researcher at HASLab (INESC TEC). I was part of the Distributed Systems group, and my research work was focused on large scale analytical query processing systems, and it was developed mainly in the scope of LeanBigData European project.

In April 2015, I finished my PhD at MAP-i (doctoral program in Computer Science). My work was developed in the context of DxT, GAsPar and PRIA projects, and focused on the development of a conceptual framework to encode knowledge used by domain experts when building high-performance libraries and applications. During the periods of March–August 2011 and March–August 2012 I was a visiting scholar at the University of Texas at Austin.

Before, I studied Mathematics and Computer Science at Universidade do Minho, where I got my BSc degree in December 2008. During this time, I was a collaborator on AspectGrid, and PPC-VM projects.
