Check out David's expertise

I am a driven and passionate Senior DevOps Engineer. Originally coming from a Software development background some 15 years ago and now with over 8+ years of experience in commercial DevOps roles.

I generally love all things cloud & automation.

Of late I've obtained a particularly in-depth knowledge of AWS, Terraform, Github actions, Atlantis, Kubernetes, Helm, Ansible, Linux, Networking, Python, and systems design.

I specialise in helping small early stage startups cutting through the noise and getting setup with AWS environments that have good foundations for growth and security.

Project Lead Developer

Broke apart a monolith and converted stack to Kubernetes on GCP.

- Helm for Kubernetes deployments, orchestrated by Circleci for continuous, seamless deployments without disruption or downtime within the app.

- Extremely important in gaming and allows me to deploy hundreds of times p/ d.

- GCP infrastructure/environments built with Terraform.

- Re-developed the monolith into ansible playbooks containers using a mixture of packer+ansible & straight Dockerfiles.

- I have implemented log shipping + host monitoring to Datadog using Fluentbit.

- Implemented GCP Cloud Armour to help detect and prevent malicious attacks and developed and refined the codebase to refine and expand features. This redevelopment agenda is live and can be found here (CAUTION NSFW) https://www.street-crime.com.
