I am a Product Manager who loves designing and building systems that make sense of data, turning them into actionable insights for people and businesses in real-time and at scale. I am thrilled about solving challenging problems in elegant and efficient ways through the use of state-of-the art tools and by having an eye for quality.

In short, I am a broadly-skilled Software Engineer that loves thinking of new ways to farm insight from data and putting it into an easy to use, high-value product.

I have over 5 years experience in building real-time, scalable analytics and data processing systems in many domains, from Telecom to Payment Processing; from stealth network monitoring to real-time analytics; from Predictive Analytics to Fraud Detection.

I have a broad technical experience although I enjoy working the most with Scala, Ruby and am always trying to learn and experiment with state-of-the-art technologies and methods.

I am quick on my feet and embrace and drive change and continuous improvement in every team I have worked with. I value agility, transparency and a focus on quality and shipping on time. I also feel at home talking to clients, users and partners looking to find new opportunities and improve our products.

IT Architecture Automatic Verification: A Network Evidence-based Approach(Link)

Proceedings of the Fourth IEEE International Conference on Research Challenges in Information Science, RCIS 2010, Nice, France
May 2010

Ensuring constant synchronicity between the IT Architecture (ITA) and the actual Information Systems (IS) without the help of automatic tools is an intractable task, especially when taking into account modern IS' rapid evolution and growing complexity and distributed nature. We propose an automatic AS-IS ITA verification methodology and framework based on deep passive network traffic analysis and logical inference rules with the goal of inferring relevant facts about the actual ITA.
