ABOUT ME
Software and Infrastructure Coach
Software and Infrastructure Coach
Pleased to meet you. I'm a Ruby developer, software architect, technical coach and infrastructure engineer, and I've been designing, developing and working with emerging technology for more than 10 years. I'm looking forward to working with you to help you improve your skills, take a new career direction, or perhaps just fill your spare time learning something new.
I'd be very happy to talk about AWS, Ruby, Linux, Docker and Containerisation, Networking (including switching and routing), Configuration Management (such as Puppet), or more general software and infrastructure concepts.
I'm a certified AWS Solutions Architect at the professional level, and a certified subject specialist in Security and Advanced Networking.

Very professional, knowledgable and thorough. Keen to provide a resolution, agreed to catch up the next day, as I am unable to test the remote end of the VPN. Would definitely recommend.
