The aim of this project was to empower our software engineering teams with self-service capabilities. The architecture, leveraging Kubernetes, can be deployed both on AWS, Azure and on-premise, demonstrating our commitment to providing a productised, flexible, environment-agnostic platform. We have integrated our deployments with GitHub Actions and Terraform Cloud, catering to varied business needs and enabling consistency and reliability across the our environments. Our focus on platform engineering as a product-centric discipline has ultimately redefined our workflow, enabling greater speed and autonomy for developers, while ensuring a robust, scalable and secure platform for our multi-tenant SaaS product and customers who require a single tenant environments.
In a significant shift, we successfully migrated from Jenkins to GitHub Actions and transitioned from GitLab to GitHub, bringing all our version control and CI/CD pipelines onto a single cloud-hosted platform. This consolidated approach not only enhanced team collaboration and streamlined processes, but it also eliminated the overhead of managing and maintaining self-hosted solutions. With this, we were able to reallocate resources and focus on our core platform, resulting in accelerated development cycles and improved productivity. The move underlined our commitment to leveraging cloud services to deliver efficient, scalable, and reliable solutions.
In my current role I champion an innovative approach where we treat platform engineering as a product team. In this paradigm, our platform is not just an infrastructural element, but a product in itself, developed and managed to deliver value to our internal customers - our developers and other stakeholders and our external customers’ production gaming environments in America and Europe.
My leadership style is characterised by strategic decision-making with a focus on thinking long term whilst fostering an atmosphere of innovation in a safe to fail environment.
I believe in leading by example, navigating challenges, and driving technological initiatives with a visionary approach.

My primary role was to automate the infrastructure and application components of the continuous delivery pipeline, while ensuring the highest quality deliverables in collaboration with the development team.
My responsibilities included working alongside developers to meet their infrastructure needs and assisting in troubleshooting both application and infrastructure issues. I was integral in automating software deployments via Bamboo and Puppet in collaboration with the release team.
I ensured the quality of our infrastructure codebase through regular code reviews and verifying sufficient test coverage. A key aspect of my role was the integration of our codebase with the development toolchain, comprising Stash, Jira, and Bamboo.
As part of my efforts to share knowledge and promote best practices, I held weekly training sessions with the operations team. We discussed a variety of topics such as infrastructure-as-code with Puppet, test-driven infrastructure with RSpec/serverspec, and containerization technologies.
In managing the Puppet infrastructure, I was responsible for its installation and configuration, implementing best practices for our Puppet codebase, and ensuring adequate monitoring and metrics with tools such as Zabbix, Nagios, Elasticsearch, and Kibana. My role, therefore, embodied a balance of technical expertise, collaboration, and mentorship, all aimed towards delivering quality products.
My work focused on Infrastructure as Code (IaC) and configuration management while providing mentorship to junior and intermediate system administrators.
Key achievements included the implementation of an automated Linux server rollout process using Cobbler, as well as deploying a Puppet-based configuration management system for over 2000 Linux nodes.
I developed custom modules for First National Bank, handling a wide array of configurations including security standards, PCI, SSH, Apache, FileSystem ACLs, Postfix, PostgreSQL, Puppet infrastructure, name resolution, AD authentication, and software like Jira, Crucible, Confluence, Stash, Bamboo, and Maven.
I also deployed community modules for managing functionalities such as host-based firewalls, log rotation, NTP, kernel parameters, nginx, MySQL, PuppetDB, and Tomcat, among others.
My role included scripting to automate tasks, such as VM creation via the VMWare API, monitoring, database refreshes, software installations, and ensuring compliance to baseline standards. This automation made us capable of deploying hundreds of VMs within minutes, pre-configured and ready for use.
I implemented Kanban within the Linux team, executed daily tasks like documentation, troubleshooting, and performance tuning. I also developed a solution to automate the refresh of the Human Resource department’s Oracle database and application servers, reducing the process time from 3-5 days to under an hour.
