Alexis Campailla

CEO

Alexis founded Janea Systems out of his passion for software engineering and solving complex technical challenges.His calling for math, science and programming was apparent from a very early age. At age 9 he started learning how to code on a Commodore 64 and within months he was already programming games in assembly language. Before graduating from high school he was proficient in C and was dabbling in graphics driver development for the IBM PC. After graduating cum laude at the university of Rome, where he also won several high-profile programming competitions, he moved to the USA after being headhunted by Microsoft, where he was part of the team that created the first version of the .NET Runtime. During his time at Microsoft he was awarded numerous patents and various publications including: “Efficient filtering in pub/sub systems”. After participating in the first 2 major releases of .NET, he left Microsoft to co-found Wishpot – a startup aimed at creating universal wishlists, later acquired by Light in the Box – where he was CTO.

Microsoft then sought his services as a consultant to help solve some of their deepest technical challenges, working on .NET, Windows, Exchange, experimental projects for the office of the CTO, and leading several high-impact open source projects for MS Open Tech. This included the Node.js on Windows initiative where he became a member of the Node.js Foundation’s technical governing body, the Technical Steering Committee. He also led the Redis on Windows project and oversaw the creation of Memurai, from the go to market strategy, and deep involvement in delivering the code for the product’s core features and improvements.

Coupled with a passion and experience in software engineering, knowing very well that the world is being eaten by software and yet a seemingly endless shortage of engineering talent, motivated him to find innovative ways to connect the best talent to the most challenging demands of the industry worldwide. Eventually leading him to recruit more like-minded people and build a team of engineering excellence at Janea Systems, where he now serves as CEO.

In his free time, he enjoys playing beach volleyball, playing music, and travelling.
