I am an seasoned and results-oriented R&D professional, with over 15 years experience. I have participated in and managed a large number of large-scale R&D projects, both commercial and academic, at the national and European levels. My main field of expertise is Quality of Experience (QoE), which deals with how users experience the services they use. QoE is a very multidisciplinary field, spanning several technical domains such as networks, media, cloud, and web, as well as human aspects, including business. I am also knowledgeable on a number of other topics, such as Data Analysis, Predictive Models, Network Performance (QoS), Network Function Virtualization (NFV), Software-defined Networks (SDN), and Network Management.
Recent Work Experience
At EXFO, I worked on guiding the transition of its Service Assurance (SA) product line to virtualized environments. This work revolved around the virtualization of network probes and their associated support infrastructure, and their integration into NFV architectures, notably ETSI NFV MANO. There were also performance issues to be addressed, due to moving the probes from specialized hardware to a COTS-based cloud context. My role involved translating the business requirements into engineering specs, dealing with stakeholders, planning development activities in an agile fashion, and architecting the solution.
I spent over ten years at VTT (first as a post-doc, then as a Senior Scientist, and later as a Principal Scientist). I was the lead for research in the QoE domain, and was active in other domains such as QoS measurement / monitoring. Besides the traditional work on quality assessment for media services, I have also worked on other aspects of QoE, most notably QoE management, and the business and economic aspects of QoE. Beyond my focus on QoE, I worked on Unified Communications (developing new mechanisms to manage presence), and Network Performance Monitoring (developing tools for e.g., passive QoS measurement, and vertical handover management). My duties, beyond the actual research, included project management, sales, and promotion of VTT’s competence in the area.
In 2008, we started building a spin-off from VTT, aiming at developing a novel, avatar-based, teleconferencing system with high-quality VoIP and secure document sharing and storage as its key defining features. The company was founded in early 2009. I was responsible for the architecture of the system, as well as the voice and document sharing functionality, including implementation work.

Skills & Proficiency
I am fluent in a number of technologies, tools and programming languages. In my daily work, I use mostly Ruby, git, R, C, Bash/Zsh, sed/awk, ex, Haskell, LaTeX, SQL, gnuplot, Clojure and other lisps. I’ve recently started using Julia for data analysis, too. I also have some experience in C++, Java, x86 and Sparc assembler, Python and Perl.
