Hello, how are you?
My name is Rhayonne and you’re viewing my GitHub profile, which includes an overview of what I use on a day-to-day basis. I’m passionate about IT and open source, and I strive to study and understand how everything works. Because of this passion, I’ve gained extensive knowledge in IT. Firewalls, networks, Windows Server, Active Directory, as well as the architecture, design and development of web software.
I hold a Master’s degree in Information Systems Management and Architecture from CESI in Caen, Normandy (Bac +5). I am always looking to acquire new knowledge. Here on my GitHub profile, you can see the personal projects I develop for learning purposes and also review concepts I have learnt in the past. If you’d like to chat, send me a private message on LinkedIn or an email; I’ll leave the links below.
If you’d like to invite me to work on a project, whether personal or professional, please get in touch too. I’d be happy to help.
