Hello!

About Me

Nice to see you here. I am Caelan, a technology professional based in Vancouver.

Like many people in tech, I have been tinkering my whole life. From a very young age I was happily doing things like getting Linux distributions running (cutting my teeth on things like LFS) to hosting my own services. 

I coached competitive gymnastics for a bit over 10 years, however when COVID came around it made that field of work a challenge. It was at this point I switched to working in tech. 
A few years later, I have established myself as a Solutions Architect, though titles like Senior Systems Administrator/Engineer, Cloud Administrator/Engineer, Projects Engineer, Sales Engineer, and others in that vein would also be appropriate - I find myself wearing a lot of hats in my daily work. 

Have any questions? Need any assistance? Feel free to reach out - either via my Linkedin or email at caelan@caelandrayer.ca

Check out my knowledge base!

I have been putting together some documentation - happy to share it with the world. Take a look (on the left toolbar/blade) and see if anything helps you out.

If there is something you are curious about and would like some documentation on - let me know!

Business Highlights

I am heavily involved in all the moving parts required to bring a new solution to full operational status. I handle everything from: engaging stakeholders to determining business needs, solution evaluations, design & architecture documents, quoting, planning & coordination, technical configuration, operational hand-offs & end user training.

I also serve as an escalation point for senior leadership of clients & internally (including VPs and C-Suite), managing issue resolution, incident response, remediation planning, and impact assessments.

Recognized by clients for my ability to clearly & effectively communicate & handle competing priorities in a sometimes stressful operational environment.
