Hands on technical leadership role, responsible for all things cloud (AWS, Azure & GCP). Managing cross team relationships between software engineers, qas, product & non tech teams.Setting expectations to the wider business on DevOps resource availability, sprint task progress & project management. Roadmap planning for platform innovations, maintenance & internal tool development. Mentoring team members, performance reviews & career planning.Managing oncall processes. Managing incidents and postmortems. Notable ProjectsDeveloped & provide ongoing support for in house ephermal environments which allow developers to create & terminate environments which mimic a production environment for a fraction of the cost, allowing them to push feature branches and test on the fly without having to rely on their local machine being setup in the correct way.Engaged in AWS cost optimisation exercise which resulted in 17% savings p/m as a result of infrastructure right sizing and properly implementing autoscaling to ensure end users don’t experience any performance degradation. Optimised pipelines for deploying core applications, allowed us to utilise one image throughout each environment for added confidence, faster deployments and cost optimisations when considering image storage.Several Python Lambda functions for internal tools to be used by the wider business.
