Hello! I'm Cristian Sirbu.
I'm a network engineer 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 can do for you, please get in touch.
My background includes enterprise and service provider networks, operational support, L2-4 testing, coding, Linux administration and mobile telecoms. Oh and I am CCIE #43453 (woohoo! :).
I very much enjoy talking about the technologies that I work with and I (and others too!) think I'm pretty good at it, be it on this website or in real life - I've been teaching at Cisco Academies and internally in the companies I've worked for.
In August 2015 I kick-started the Ireland 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 I organize together with Donal and our varied and very generous hosts (Intercom, Airbnb, Google, Workday, Facebook). Some of the story is documented here.
Aside from networky things, I love Linux 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 will be technology related, with a heavy bias towards networking (no surprise there, huh?). It is hosted on Debian Linux, served by Nginx and generated with pelican and python.
