LIP6 at UPMC Sorbonne Universités 2008-2010

Study Engineer

Contributing to the open-source code base as developer, writing technical reports and proposals, following up on interns, as well as performing system administration of a heterogeneous global-scale platform.
Project:

• OneLab Project: developing, maintaining and federating a large-scale, general-purpose platform based on open-source PlanetLab software.

Scientific Software:

• MySlice and PlanetLab: charged of designing and implementing a set of tools for optimising resource allocation procedures over PlanetLab, a highly distributed and heterogeneous platform.

GPRT team at Federal University of Pernambuco 2004-2007

Study Engineer

Development of network traffic analysis tools, P2P system and self-protection security architecture. The development relied on DHT, probability statistics theories, data mining and information theory techniques.
Projects:

• BTMA: Characterization of Internet traffic by extensive statistical analysis and formal modelling.
• Robust-IP: Design and developing of a self-reliant security architecture.
• RNP’s GTP2P Project: providing a middleware (XPeer) to improve the development and deployment of new P2P systems.

Scientific Software:

• Analyser-PX and NTPC: developed a set of tools for capturing and classifying P2P traffic based on communication partners and users behaviour, by using data mining and information theory approaches.

Publications:

• five papers, one master’s dissertation and one tutorial (further information in my research page).

Department of Health of the Brazilian State of Paraíba 2002-2003

Chief Networking Engineer

Network design, deployment and management of distributed and heterogeneous systems with a focus on reliability and security. The network was spread across 223 different cities, mostly administrated remotely.
Project:

• Network project: design and deployment of network infrastructure of the main site and remote networks by relying on a top-down design approach.
