Short Bio

I'm a PhD student at the Software Evolution and Architecture Lab led by Harald Gall since September 2016.

In 2013, I received my Bachelor Degree (summa cum laude) from the University of Sannio (Italy) with the thesis entitled "Mining of Methods' Descriptions from StackOverflow", where I developed CODES, an Eclipse plugin that automatically extracts methods' descriptions of Java Systems from discussions in StackOverflow. In 2014 CODES was awarded with the Best Tool Award at the 22nd IEEE International Conference on Program Comprehension (ICPC), in India.

In 2015 I stayed for four months in Amsterdam (Nederland) to do an internship at ING NEDERLAND. I conducted a research work inside the Continuous Delivery team (partially funded by ERASMUS+ program). Main Task: investigation of the practices adopted by DevOps teams during the software development and discovering of new ways to improve the software release process.

In 2016, I received my Master Degree (summa cum laude) from the University of Sannio (Italy) with the thesis entitled "Build Failures in Continuous Delivery: a Case Study at ING Nederland".

Research Interest

Continuous Delivery (CD) has been introduced by the Agile movement to favor frequent integration and delivery of new (incremental) versions of software systems. In this context, each update go through a CD pipeline with the aim of detecting defects as early as possible, reducing the cost and risk of delivering bad changes.

I'm interested in supporting developers while dealing with CD breaks (e.g., build failures) and developing new approaches to prevent them.



LEAN Approach

I try to follow this methodology in the research (and in daily life as well) 

  1. Think about improvements/ideas
  2. Measure them when applied to a real context (discuss with others)
  3. Learn about faults to refine the previous idea (accept good suggestions from other people)
