• As a member of the routing team I am designing, implementing and maintaining the routing control plane for EOS (Arista's Extensible Operating System).
• Contributing to add new features to Arista's implementation of protocols such as BGP, VPN and RSVP.
• Designing, implementing new features to meet performance, scale and quality requirements, and to strictly adhere to RFC specifications.
• Ensuring automated testing is always added together with each new feature.
• I am involved in a constant effort to maintain and improve the current codebase.
• Participating in a rotation to handle and resolve customer escalations.

Vancouver, Canada Area

• Developing the backend software for network protocols like OpenConfig, BGP, MPLS.
• Designing, implementing and maintaining sub-components of the BGP and OpenConfig servers.
• Documenting the behavior of the system.
• Maintaining sub-systems of the backend.
• Mentoring interns.
• Participating in a rotation to handle and resolve customer escalations.

Dublin, County Dublin, Ireland

• Developing the OpenConfig daemon for vendor-independent network configuration.
• Adding support of BGP routing YANG models to OpenConfig, mapping them to Arista's internal representation (Golang).
• Maintaining and optimizing the OpenConfig application (Golang).
• Writing integration tests (python).
• Writing manuals and training colleagues about OpenConfig.

Dublin, County Dublin, Ireland

• I worked as a developer on IBM SQL-on-Hadoop solution, Big SQL.
• Working on the front-end, protocol, storage layer, backend in a very large C++ codebase.
• Implementation of the binary collation, for preserving the string comparison semantic of the Hadoop ecosystem inside the DB2 query engine.
• Design and implementation of Complex Data Types (arrays, structs, maps):
• Tuning and development of the query Optimizer, in order to leverage the potential of the query engine accessing the Hadoop ecosystem sources, like Hive and HBase tables.
• Fixed performance issues impacting customers.

Udine Area, Italy

• I worked as a Software Architect in several different projects with partners and customers.
• I helped define the architecture and deployment of software infrastructure of High Performance Machine.
• I benchmarked systems for tenders and for Top500 and Green500.
• I brought up prototypes of HPC systems.
• I developed firmware for HPC systems, including Board Management Controllers.
• I contributed to the development of firmware for FPGA-based 3D Torus.

Development of Forge Engine, a multi-platform Game Engine.

Milan, Lombardy, Italy

• Development of Forge Engine, a multi-platform Game Engine.
• Design and implementation of the Rendering Engine. It was based on a graph of shaders that was reconfigurable during run-time. The Engine runs on OpenGL, OpenGL ES and DirectX. It was successfully implemented to both.
• Design of the database describing the game's status. The database was designed to support multiplayer, so it was designed to support versioning, transactions, pruning and concurrency.
• Design of the graph system mapping the game database into the visual representation on all clusters. The system has been developed to support concurrency and to be easily tunable by the artists producing the game assets.
• Rendering engine, gameplay programming and sound engine for the iOS game 'Vikings can Fly!'

Ferrara, Emilia-Romagna, Italy

• I collaborated on several projects about massively parallel machines and I was involved in teaching activities.
• I designed and developed system software for custom parallel machine apeNEXT (scheduler, system libraries, compile chain tools).
• I implemented tools for static and runtime profiling of code.
• I implemented Linux kernel modules.
• I developed and optimised physics applications for parallel architectures (Monte Carlo simulations, Lattice Boltzmann methods).
• Extensive performance modelling.Projects:
