Salvatore started his career in 1997 as a security researcher, writing the hping (https://en.wikipedia.org/wiki/Hping) security tool and inventing the Idle Scan (https://en.wikipedia.org/wiki/Idle_scan). Later he worked on embedded systems, focusing on programming languages research and creating a small footprint Tcl interpreter, which is still in active development. With a colleague, Salvatore created the first two Italian social applications in partnership with Telecom Italia. After this experience, he decided to explore new ways to improve web app development, and ended up writing the first alpha version of Redis and open sourcing it. Since 2009, he has dedicated most of his time to developing Redis open source code.
Over the years, Salvatore has also created a number of other open source projects ranging from software defined radio, to line editing tools, to children development environments. He lives in Sicily, Italy.
