Career Timeline

Apprentice at a Telecoms company (O2). Then specialised in Service Management ITIL as the Service Manager for retail store systems.


Got contracted out to Tesco Mobile as a Supplier Manager, started to shuffle towards the systems side of that and ended up becoming a DevOps Engineer in their in-house dev team. Then in 2020 I left Telefonica and came to Glean as a Sr DevOps Engineer.


Specialist Skills

Make a banging Neapolitan pizza, AWS, GCP, DevOps tools in general. I do love PHP but that's a dirty secret.
