Software Engineer & Researcher

About

Currently in the final steps towards my PhD degree, I would like to pursue a career as a software engineer where I can design and develop new features for real-life products. I have 5+ years of experience in software development and computer science RD. Having worked in multiple countries and in different projects have given me the versatility to adapt well to different environments and to quickly learn new technologies as the project evolves.

Since September 2013, I am a PhD student at the Communication and Distributed Systems group, University of Bern, under supervision of Prof. Dr. Torsten Braun. I am currently working on efficient multimedia content retrieval methods for Content-Centric Netorking.

Before starting my PhD, I worked as a researcher and software developer at COPElabs, in Lisbon, Portugal. There, I developed an application for testing data transmission for intelligent transportation systems and I also developed an Android application for wireless contact tracking. Before that, I interned at the Distributed Information Systems Laboratory, EPFL, where I developed an application for social (Twitter) and sensor (WeatherUnderground) data fusion in Hadoop. I also interned at Fiat SpA in Turin, Italy, where I developed a Microsoft .NET application that helped the supliers quality team to improve their data management.

I obtained my Master's degree at Politecnico di Torino, Italy and my Electrical Engineering degree (BSc) at Universidad Central de Venezuela, Venezuela.

NetCodCCN: a Network Coding approach for Content-Centric Networks

Jonnahtan Saltarin, Eirina Bourtsoulatze, Nikolaos Thomos and Torsten Braun.
IEEE INFOCOM 2016 - The 35th Annual IEEE International Conference on Computer Communications.

In this paper we propose the use of Network Coding in Content-Centric Networking (CCN) to improve multi-path communication (e.g. LTE and WiFi). Our protocol, NetCodCCN, improves data retrieval times without the need of central coordination. Network coding also bringss improved resiliency to errors and throughput gains.

Social and sensor data fusion in the cloud

Surender Reddy Yerva, Jonnahtan Saltarin, Hoyoung Jeung and Karl Aberer.
IEEE MDM 2012 - The 13th IEEE International Conference on Mobile Data Management

This paper explores the potential of fusing social and sensor data in the cloud, presenting a practice travel recommendation system that offers the predicted mood information of people on where and when users wish to travel. We performed heavy ETL as well as filtering jobs, resulting in 12 million tweets over four months. We then derived a rich set of interesting findings through the data fusion, proving that our approach is effective and scalable, which can serve as an important basis in fusing social and sensor data in the cloud.

P2P video streaming with inter-session network coding

Jonnahtan Saltarin, Nikolaos Thomos, Eirina Bourtsoulatze and Pascal Frossard.
IEEE ICME 2011 - The International Conference on Multimedia and Expo.

We present a novel receiver-driven p2p system for delivery of multiple concurrent time constrained data streams in overlay networks. We propose an effective combination of rateless coding with intra- and inter-session network coding to efficiently exploit the path diversity in the streaming overlay. The transmission strategy is determined based on the availability of data sources and the demands of the children nodes.
