Sometimes I write about my infosec research and projects: medium.com/@gerrygosselin


I’m a Healthcare technology geek by trade and security researcher by night. I spent a decade as a web developer, systems integration hack, and network management systems engineer coding in: Perl, python, Java, javascript and CSS. I then spent a decade in healthcare tech working with IT infrastructure. I love software-defined networking and storage, and promote infrastructure-as-code. I stand on a tiny soapbox pushing an agenda of patching, network segmentation, and Active Directory segmentation in vulnerable environments. I'm also a business analytics geek. Recently, I’ve taken an interest in software-defined radio, Ghidra, and programming in C and assembly (x86-64, ARM, 8051) to further a passion for IoT reverse engineering and hardware hacking. I write about my findings on Medium to help others and to force myself to think through what I’ve learned and question what I truly know.

Happily mangling data and containers at Cisco, they don't pay me enough to talk for them. I'm also doing the network at FOSDEM for a few years already.

Mostly using Golang/Python in development and ML. Of course using Linux, also a infosec and general networking guy, used to do a lot more Common Lisp and Debian.

Multilingual, so expect retoots and content in a mixed set of languages... I have a 'Belgian' account (mostly Dutch/French) at @pvaneynd

Java/Python/... - full snack developer - like to know what's behind and driving a thing

My spare time I spent on (alphabetical order)
- coding (mainly Python and Java, others on need)
- cooking, baking and patisserie
- cycling
- ESP32, Raspberry and other SBC's
- security (to the extend not to feel entirely unsafe ;-) )
- SciFi (books and movies)
- anything else which catch my interest

note: Don't expect me to be THE guru in one of them. Not that I don't want to be, but spare time is limited.
