Automating Cloud, Empowering Teams.
About me
I am Asttle Joseph, a DevOps Engineer based in London, UK, with over 5 years of experience in the software industry. I specialize in cloud infrastructure (AWS, Azure), containerization (Docker, Kubernetes), CI/CD automation, and observability solutions. I recently completed my MSc in Computing and Technology from Northumbria University with first-class honours. I am passionate about building scalable, reliable, and secure systems, and have a proven track record of delivering robust solutions in fast-paced environments.
My expertise includes deploying AI services in the cloud, architecting GitOps workflows with ArgoCD, leading EKS/AKS cluster upgrades, orchestrating multi-cloud migrations, and implementing comprehensive observability stacks using OpenTelemetry, Jaeger, Prometheus, and Loki. I am certified as an AWS Solutions Architect Associate and a Kubernetes Administrator.
I am always eager to learn new technologies and collaborate with teams to drive automation, efficiency, and innovation. Let's connect if you are looking for a DevOps Engineer who can make a difference!
