About

I collaborated on the European Community-funded GORDA project, whose goal was to foster database replication as a means to address the challenges of current database systems. I worked on providing GORDA with a web-based graphical monitoring and management console that leverages JMX capabilities. 

I was also involved in the P-SON project, specifically in developing applications for the NeEM epidemic multicast protocol. In this context, I worked on a RSS feed caching and dissemination architecture that leverages p2p networks to accomplish its task and later on a generic P2P content-push architecture based on Web feeds and social network services, which served as a basis for my Master’s dissertation work. I also worked on an epidemic dissemination protocol that takes advantage of participants’ shared interests without actually disclosing them. 

In the context of my Ph.D, my work was focused on how to bridge the gap between traditional database-centric applications and the promises of high availability. 

Currently, I'm a part of the CloudDBAppliance european project, and also have been collaborating with CPES in the context of the UPGRID and InteGRID european projects.

A Comparison of Message Exchange Patterns in BFT Protocols: (Experience Report)

Abstract
The performance and scalability of byzantine fault-tolerant (BFT) protocols for state machine replication (SMR) have recently come under scrutiny due to their application in the consensus mechanism of blockchain implementations. This led to a proliferation of proposals that provide different trade-offs that are not easily compared as, even if these are all based on message passing, multiple design and implementation factors besides the message exchange pattern differ between each of them. In this paper we focus on the impact of different combinations of cryptographic primitives and the message exchange pattern used to collect and disseminate votes, a key aspect for performance and scalability. By measuring this aspect in isolation and in a common framework, we characterise the design space and point out research directions for adaptive protocols that provide the best trade-off for each environment and workload combination. © IFIP International Federation for Information Processing 2020.

Building a Polyglot Data Access Layer for a Low-Code Application Development Platform: (Experience Report)

Abstract
Low-code application development as proposed by the OutSystems Platform enables fast mobile and desktop application development and deployment. It hinges on visual development of the interface and business logic but also on easy integration with data stores and services while delivering robust applications that scale. Data integration increasingly means accessing a variety of NoSQL stores. Unfortunately, the diversity of data and processing models, that make them useful in the first place, is difficult to reconcile with the simplification of abstractions exposed to developers in a low-code platform. Moreover, NoSQL data stores also rely on a variety of general purpose and custom scripting languages as their main interfaces. In this paper we report on building a polyglot data access layer for the OutSystems Platform that uses SQL with optional embedded script snippets to bridge the gap between low-code and full access to NoSQL stores. © IFIP International Federation for Information Processing 2020.
