Some examples of our work:

Alpha/HTB: designed and implemented multi-AWS-account VPC architecture using IAM role based cross-account authentication to simplify access and traceability whilst keeping billing for different environments separate.
Rationalised the existing flat, classic EC2 based setup, transcribed the deployment process from Jenkins/Rake to RunDeck/Ansible and migrated the live systems to the new VPC. Worked in close co-operation with Sift Digital Dev team.

Coull: got up to speed quickly with Coull’s BASH based, hybrid cloud infrastructure management framework (ZPF) in order to deploy Puppet backed web servers and Redis and ElasticSearch clusters. Rationalised a number of Jenkins jobs

University of Bristol, research IT dept: brought in at short notice to assist the Dev team to deploy a high-profile application against a hard deadline. Hit the ground running with Vagrant, Fabric and Puppet 3 & 4
