Stefan leads, maintains, and refines Python and Django open source software projects. He also deploys and maintains servers and various internal services such as the mail server and the, now deprecated, Jitsi video-conferencing system and IRC chatbot. He is driven by his attention to detail and likes to spend time perfecting software.

He began his software development journey at a young age. Stefan liked tinkering with tech (often breaking it) and then he moved on to developing small programs in Visual Basic, C#, and C++.

Stefan developed his passion for Free / Libre Open Source Software while studying in Arlington, Virginia where he met Jeff Elkner, his Computer Science teacher at Arlington Career Center. His software development journey gained momentum when he was offered an internship at NOVA Web Development in 2019.

During his internship, Stefan led the redevelopment of LibreOrganize, an association management system that was based on Tendenci, from the ground up. He also developed Business Tracker, a time-tracking and invoicing system, and worked other internal tools.

He likes being helpful to his co-workers and is now working on larger-scale systems for collecting data and generating reports as well as some smaller-scale projects. One such system is used by Gallaudet University to collect data from researchers and aggregate it in a PDF which is sent to the U.S. Congress.

Stefan is from Bucharest, Romania and is pursuing a Bachelor's Degree in Computer Science at Newcastle University.

In addition to being both a user and programmer of Free / Libre Open Source Software, Kevin Cole has spent most of his life advocating its use, particularly its use by students, teachers, librarians, and others in academic settings. "If you want technological innovation, give people the ability to look inside everything, take it apart and put it together in new and unexpected ways."

As part of that philosophy, he co-founded NOVA Web Development to help young developers establish themselves in the industry. Under the NWD banner, he has developed a database for tracking research projects at a local university, and a "aural virtual reality" lab, designed to educate new hearing aid and cochlear implant users by immersing them in sound environments. He continues to tutor students from ages 13 to 75.

In his increasingly ample spare time, he has shifted his focus towards music and music technology. He is also a charter member of the second oldest hackerspace in the U.S. where he teaches adults about 3D design and 3D printing, as well as microprocessor technology such as the BBC Micro:bit and the Raspberry Pi.
