Hi🖖, I’m JayJay 😃.
A DevOps practitioner and Linux enthusiast, dedicated to the art of building, breaking, and documenting complex systems. Whether I am orchestrating containers, managing cloud infrastructure, distro-hopping between Fedora, Ubuntu, CentOS, Mint, Zorin or Parrot machines , I believe in turning technical complexity into clear, actionable “Docs-as-Code.”
The Lab🔬 & The Toolkit 📐
My roots are firmly in the Linux ecosystem, and I have spent years sharpening my skills with virtualization tools like VMware, VirtualBox, and Docker. Currently, my “digital laboratory” is focused on:
Cloud Platforms: Deepening my expertise across AWS, GCP, Vultr, Digital Ocean and Linode.
Infrastructure as Code & Automation: Mastering Terraform for provisioning, Ansible and Puppet for configuration management.
Orchestration: I am currently on a journey to master Kubernetes, with a specific focus on preparing for the CKAD (Certified Kubernetes Application Developer) certification.
CI/CD & Pipeline Automation: Building efficient delivery workflows using GitLab CI and Jenkins to automate testing, integration, and deployment cycles.
Observability & Monitoring: Ensuring system reliability with Prometheus and Grafana for metrics and visualization, alongside Nagios and Zabbix for robust infrastructure health checks.
Virtualization & Cloud Infrastructure: Extensive hands-on experience managing virtualized environments with VMware, VirtualBox, and Vagrant, complemented by building oVirt clusters and maintaining familiarity with OpenStack architectures.
Workload Orchestration & Infrastructure Security: Orchestrating distributed systems with HashiCorp Nomad, streamlining service networking with Consul, implementing centralized secrets management with Vault, and automating golden image creation across platforms using Packer.
Service Mesh: Exploring Linkerd and Istio to manage microservices communication, traffic splitting, and secure service-to-service interaction.
Secret Management: Prioritizing security by using HashiCorp Vault to centralize and protect sensitive credentials across infrastructure workflows.
Containerization & Runtimes: Beyond Docker, I am exploring containerd and CRI-O to better understand the low-level mechanics of how Kubernetes executes containers.
Static Site Generation: My commitment to “Docs-as-Code” is powered by Hugo, which I use to maintain my technical blog and project documentation.
📍🗺️ The Roadmap 🎯
I am a firm believer in continuous learning. Beyond my daily hands-on projects, I am currently working toward the AWS Certified Solutions Architect certification to further formalize my cloud architecture skills. I document my learning process here, at HalfKnown.CO.Uk AKA JayJay’s DevOps Diaries, because I believe that if it isn’t documented, it didn’t happen.
🗫 Community & Networking 𐦂𖨆𐀪𖠋
I’m a regular fixture in the London tech scene, frequently attending meetups like London DevOps, Linux Recruit, and London Linux & Drinks. I’m also a consistent attendee at industry-leading conferences at the ExCeL London, including the AWS Summit, which I’ve attended every year for the past four years. Engaging with the wider engineering community is a core part of how I stay sharp and keep up with the latest innovations in the cloud-native space.
👨🏻💻 Beyond the Terminal 🎾જ⁀ ➴ 🏸˙⋆✮
When I’m not deep-diving into infrastructure or scripting automation, you’ll likely find me on the dance floor. I am dancer 🕺🏽, an avid practitioner of Cuban Salsa 💃🏻, deeply embeded into latin vibe, music 🎧 and concerts👨🎤. It keeps me sharp, focused, and reminds me that even in the world of IT, rhythm 🎼, coordination, and community are essential.
Lastly, I have a real passion for staying active outdoors, with a special love for park games 🥎, badminton🏸, pickleball 🤾♀️ and padel 🎾🥎. I’m a firm believer that stepping away from the screen for a bit of friendly competition is the best way to recharge, so I’m always looking to encourage my colleagues to head out for a match whenever the weather is right. It’s a fantastic way to build team spirit, clear our heads, and enjoy the sunshine together 🏝️🍹⛱️🌞.
🌐 Let’s Connect 🤝 ⇄
I’m currently focused on expanding my expertise in service mesh, CI/CD, and cloud automation. If you’re into DevOps, Linux, or just want to discuss the latest in cloud infrastructure, I’d love to connect.

One last thing, I am an Idoma boy, not that it matters, but it sure feels good to know. LOL
