Hello! I'm Cristian Sîrbu.
I'm a network architect and a consultant, currently based in the beautiful city of Dublin. I do love traveling and solving problems, so if I there's something I could do for you, please get in touch.
A bit of background
Throughout my career I've seen all sorts of networks, operated a bunch of them on a day to day basis, offered support to various customers, got my CCIE (#43453) digits, wrote designs, argued over many colourful scribbles on whiteboards, taught Routing & Switching to many engineers, developed L2-4 testing software, coded anything from quick and dirty scripts to webapps, automated what I could and manually configured what I couldn't, had fun with Linux for both servers and my own PCs, and (because you're already wondering if there's an end to this) helped launch 4G/LTE for a mobile provider.
In August 2015 Donal and I kick-started the Irish Network Operator Group, an inclusive, open, and healthy Community of Practice around all aspects of network engineering. It has grown to incredible numbers and really awesome meetings, which we organize together with a bunch of volunteers and our varied and very generous hosts (Intercom, Airbnb, Google, Workday, Facebook, Arista, Riot Games). The story is introduced here, continues with a report in 2016 and the latest update is in talk format in 2018 at RIPE76.
Aside from networky things, I love open-source and enjoy a spot of python every now and then. When it comes to music I am very picky and I can't have enough of science fiction and fantasy. I love reading, hiking, table tennis, travel, boardgames, and generally more things than I can fit in one life. But I keep trying.
This is my website and you can find the story behind its current incarnation here. Most articles are technology related, with a heavy bias towards networking and systems engineering. It is hosted on Debian Linux, served by Nginx and generated with pelican.
