• I was part of a brand new platform team for a >10y organization that built an internal cloud platform based on Kubernetes and AWS
• > We built our own VanMoof-specific Kubernetes platform on top of EKS with batteries included: networking (Cloudflare+AWS LB controller), monitoring (Prometheus+Grafana+Loki+Mimir), authentication & authorization (Cloudflare Access+Okta), continuous deployment and integration (ArgoCD+Atlantis)
• > We created and owned a unified access controls workflow for AWS, Github, Kubernetes, Cloudflare and Okta in-code. Managers, engineers and IT all used pull requests (and approvals) to update permissions for their colleagues and reports
• > Did internal DevRel for the platform - every deliverable was also accompanied by an announcement, presentation+workshop/demo and getting started guides, published in internal channels and the Engineering Handbook that I kickstarted. Onboarded and educated 5+ developer teams to Kubernetes and Terraform
• > Automated update cycles using a combination of Dependabot and Github Actions: 3-5 PRs per day were automatically validated, approved and merged with no human intervention
• > Created a culture of working in public, as meetings and decisions of our team were made in the open, and users tuned in to listen or take part

• Zivver's scaleup stage was an excellent opportunity for me to work with both people and tools to deliver process and infrastructure improvements.
• Some of the things achieved in my time at Zivver:
• > Took a release process from a monthly (or bimonthly) to a daily release cadence, achieving no-downtime deployments on the way
• > Set up automated vulnerability scanning DevSecOps pipelines across backend (Scala-sbt), frontend (Typescript-npm) and .Net ecosystems into CycloneDX SBOMs
• > Set up automated dependency updates across Docker, GItlab, Terraform, Sbt
• > Containerized a largely monolithic Scala Dropwizrd backend for delivery in ECS and also took its build time down from 55m to <20.
• > Created a primary collaborative docs space for engineers at Zivver: The Engineering Handbook, and organized presentations to educate developers on infrastructure, as well as an AWS Immersion Day
• > Awarded Zivver's first ever "Like a Rocket" award for my cross-team impact as a member of the backend, security and DevOps teams
• Keywords: Gitlab, Gitlab CI, sbt, npm, maven, JVM, Dropwizard, Scala, RAML (I know :/ ), ElasticSearch, Logstash, Kibana, Ansible, Terraform, Grafana, Prometheus
• AWS EC2, ECS, Fargate, S3, SES, SQS, Cloudwatch, Cloudfront, most of the AWS stuff

• We founded a SaaS company with a strong focus on automation and DevOps workflows. We proposed and implemented a system for stock management and automation.
• Features include:
• > Completely automated testing and deployment, using a series of CircleCI pipelines and Kubernetes environments
• > Fully virtualized, scalable, MQ-based microservice architecture
• > Support listing of stock across multiple channels such as Amazon or Ebay with minimal implementation required
• This has been a pivotal project for the startup we founded and I led a team of 3 developers to deliver it.
