About me

I am passionate about technology and software development. I love to develop intuitive, performant, and highly interactive web applications for the representation of Internet Big Data used to guide decisions and to facilitate day-to-day Internet operations.
Below you will find some of my projects used every day by many internet operators world wide.

Experiences

Software Engineer (Research and Development) at RIPE NCC

August 2013 - present (Netherlands)

My role is to Research and Develop useful web applications for the daily "Internet administration" process.
I'm collaborating in the RIPEstat project (the largest Internet data resource) and RIPE Atlas project (the largest Internet measurement network).
As a researcher, my objective is to study the real use cases and to find clear, complete, and condensed visualizations for the data. As a developer, I have to fit this visualizations in cross-browser totally client-side widgets, paying great attention to usability, quality of the code, evolvability, architectural decisions, and performances.

The RIPE NCC is one of five Regional Internet Registries (RIRs) providing Internet resource allocations, registration services and coordination activities that support the operation of the Internet globally.
RIPEstat is a web-based interface that provides everything you ever wanted to know about IP address space, Autonomous System Numbers (ASNs), and related information for hostnames and countries in one place.

Research Collaborator at Roma Tre University

January 2012 - July 2013 (Italy)

Researched data correlation and data visualization approaches, facing challenges related to client and server side performances on large amounts of data.
Designed and developed many visualization tools, including BGPlay.js, the leading web application for visualizing BGP evolving networks.
Projects: BGPlay.js, TPlay, BGPlay3D

BGPlay has been integrated in RIPEstat in May 2013 and presented by me during the RIPE 66 meeting. You can find the presentation (pdf + video) here.

Freelance web developer and system administrator

2005 - 2012

Requirements analysis and development of web sites, content management systems, and e-commerce. Administration and hardening of in production Linux servers, virtual servers, and databases.
Integration of software/services (COTS) and interaction with third-party hardware (e.g. barcode readers/writers).
Owner of a streaming platform for business customers.

Intern at Business-e S.p.a. (ITWAY Group Company)

June 2009 - December 2009 (Italy)

Analysis and development of a tool supporting IT security experts during penetration tests. The tool learns and visually suggests probable vulnerabilities.

Some Projects

geo.ripe.net

October 2017

[ API ]

geo.ripe.net is a set of APIs providing IP geolocation. I developed this platform trying to merge together various approaches for IP geolocation, in order to improve the final output quality. Among these, the service include active geolocation based on latency measurements with RIPE Atlas. This project is now the official RIPE NCC's IP geolocation service for infrastructure.

OpenIPmap

October 2017

[ Article | RIPE 75 presentation ]

OpenIPmap is a web application for the visualisation of multiple traceroutes on a map. One of the main goal of the tool is to support people in correcting/crowdsourcing of IP geolocation. The tool provides all the data enrichment supported by TraceMON.

TraceMON

July 2016 - ongoing

[ Article | Github ]

TraceMON is a client-side tool for monitoring and investigating reachability and performance of one or more targets in a network. It uses traceroutes collected by the RIPE Atlas project or third party repositories for inferring network topology and characteristics of the various network component involved.

LatencyMON

September 2015

[ Article | Github ]

LatencyMON is an interactive tool designed to easily visualise and compare multiple latency trends collected by groups of RIPE Atlas probes.

RIPE Atlas streaming

January 2015

[ Article ]

The streaming data service allows you to tap into the real-time data flow of all the collected public results of the biggest internet measurement network in the world.

DNSMON

November 2013

[ Official page ]

DNSMON provides a comprehensive, interactive, and up-to-date overview of the quality of the service offered by high-level Domain Name System (DNS) servers.

It is part of the services offered by RIPE NCC. The dynamic visualization and the data aggregation allow the user to gradually move from the complete overview to details. The tool offers additional features to help the operators to solve problems. It uses the RIPE Atlas active measurement network to provide an up-to-date service overview of all DNS root and many Top-Level Domain (TLD) name servers. An important feature is the ability to view historical data. This allows quick analysis of both past and present DNS issues. DNSMON measures DNS performance between site that host RIPE Atlas anchors and those where DNS servers are installed.

BGPlay

January 2012 - ongoing

[ More info | Github | Demo ]

BGPlay provides a graphical and intuitive representation of a portion of the inter-domain routing and its evolution over time. BGPlay.js is an open-source web application, entirely developed in JavaScript. Its core has been released as a Framework for the shaping of tools for the visualization of evolving data which can be described in terms of graph components.

TPlay (now Radian)

June 2013 - ongoing

[ Official page ]

Radian is a web application for the visualization of traceroute measurements. It allows to look at the network at different abstraction levels and to animate the evolution of network paths during a selected time interval.

The system has been tested on traceroutes performed by RIPE Atlas Internet probes, that continuously perform large scale active measurements towards several Internet services. This tool was presented at the annual Graph Drawing conference in 2013 and to the LEONE project meeting in the same year.

SoS Monitor

EUhackaton, 24-25 September 2013

[ Demo | See on visualizing.org ]

State of Surveillance Monitor is a visualization project that integrates various source of data in order to compare two different perspectives: (i) the surveillance mechanisms the governments are deploying, versus (ii) the awareness of the citizens and the media.

This project has been presented at the EUhackaton 2013.

BGPlay3D

May 2013 - September 2013

[ Official page ]

BGPlay3D is a tool based on BGPlay.js which offers a 2.5D visualization (WebGL) by implementing the innovative Ribbon Representation metaphor for flows in networks.

You can find additional information on the official page, including a third-party mockup implementation: BGPlay3D.

3DICOM

December 2011

[ Demo | Github ]

3DICOM allows the user to build and navigate in the browser a 3D model of an organ strarting from a biomedical image (DICOM, e.g. MR, CT)
