Work Experience

Software Developer

2020 - PRESENT
ReaQta
  • Re-engineered and consolidated a tool for dynamic malware analysis and integrated it with the company's software suite (Python 3).
  • Developed a tool to automate testing of offensive techniques selected from the MITRE ATT&CK framework categorization by tactic and technique (Python and PowerShell). The tool's main purpose was to measure ReaQta EDR software detection capabilities.
  • Integrated a tool for automatic creation of a realistic, multi-host, virtual laboratory, including Active Directory domain-joined Windows and Linux machines.
  • Emulated a real, advanced persistent threat (APT) in preparation for MITRE evaluations. This activity included thorough research on FIN7/Carbanak threat actor offensive capabilities and automatic testing of the collected offensive techniques.
  • Developed the company's Linux endpoint monitoring agent.
Technologies: Python, SQL, Windows PowerShell, Docker Compose, Docker, Alembic, Celery, Python 3, Linux, C++

Software Developer

2019 - 2019
Sistemi & Automazione
  • Conducted research on an ontology matching problem and the existing state of the art on how to approach and solve the problem efficiently.
  • Devised a tool for automatic data type detection using machine learning. The tool receives data in tabular form and tries to guess each column data type, providing hints on type matching to the user.
  • Conducted a penetration test on the company's internal network and exposed web applications.
Technologies: ETL, Python, Machine Learning, Docker, Pytest, Alembic, Scikit-learn, PostgreSQL, Flask-Marshmallow, Flask-RESTful, Flask, Python 3

Software Developer

2012 - 2019
National Research Council of Italy
  • Developed software for distributed cracking of various cryptographic protocols (OpenGPG, OpenPGP, BitLocker, and AES Crypt).
  • Designed and integrated a multi-component software solution for distributed shape optimization in the aeronautical field, using C++ and Qt framework.
  • Coded a tool for optimal path computation and visualization using GPUs (C++ and CUDA).
  • Designed and implemented multi-component software for dynamic malware analysis based on virtualization and introspection, using Python and C language.
Technologies: SQL, C++, Docker, C, PostgreSQL, CLucene, NVIDIA CUDA, HTCondor, Qt 5, Python, Linux

RBF4AERO

https://www.youtube.com/watch?v=eThibFzEPNI
The RBF4AERO project was designed to tackle all aspects related to aircraft numerical design and optimization by making the computational fluid dynamics (CFD) model parametric through an innovative shape optimization tool based on a high-performance, mesh-less morphing technique.

My role in this project was to devise and implement a multi-component platform that integrated various software technologies in order to scale the computation of shape modifications in a distributed cluster of nodes. Although I generally focus more on the back end, in this project I worked as a full-stack developer, as I also coded a desktop application based on Qt framework.

Sandbox for Malware Multi-analysis

The main scope of this project was to ease the work of ReaQta's threat intelligence team with the daily analysis of in-the-wild threats. In this project, I integrated ReaQta's endpoint monitoring solution with other open-source security tools in order to automate malicious document and executable analysis.

The project is composed of various back ends (one for each integrated security solution) and a REST API that receives analysis requests and schedules required Celery tasks. I also implemented a Slack bot that enables analysts to efficiently communicate with the platform and share analytic results with other members of the team.
