Christer is one of the most capable guys I know. He's made massive contributions to Open Source, and the IT communities, and to Adobe in general. This company will be less great without him. Everyone who knows him here will agree. I'm glad we crossed paths, and look forward to hearing about what he does next!
Christer is one of those one in a million guys that enjoys what he does so much I often wonder if he considers where he disappears 8 hours a day 'work'. A guy that is not afraid to tackle complex problems out of his wheelhouse and come back for seconds. A guy who makes the right technical decision that will benefit the company's infrastructure for years to come despite corporate politics that stand in his way. This is the guy you want on your team. We made a global decision at Adobe to embrace SaltStack at Adobe and he showed up to the salt mine (no pun intended) with a shovel and a hat ready to work becoming Adobe's resident salt expert in the process. I have highly enjoyed my time having Christer as a peer and look forward to an endeavor in which we can work together again.
Christer is a dedicated, hard-working and loyal colleague. I value his opinion when I ask. He provides timely and useful answers with research and results to back up his claims. Christer provides a very good vibe around the office and with our other colleagues. He's always positive and interested in helping those around him succeed, no matter what the subject. He dedicates much of his personal time to making sure those who are interested have the knowledge he knows he can provide. Christer is an excellent instructor in my experience.
