Summary
🤩
RockstarJosh Kellendonk is a Principal Cloud Architect based in Okotoks, Alberta with a decade-plus of hands-on experience building serverless, multi-tenant SaaS platforms and cloud-native infrastructure. He’s been using AWS since 2008 and Kubernetes before 1.0, combining deep platform expertise with practical engineering in TypeScript, Go, and Python (and a taste for Rust). Josh architects resilient, secure, cost-conscious systems—designing data pipelines, GitOps CI/CD, and IAM/VPC security—and has integrated ML services like Amazon Bedrock and OpenAI into production workflows. He’s an active open-source contributor, notable for enhancements to projen and the AWS CDK that speed deployments and improve developer ergonomics. Colleagues rely on him not just for architecture but for mentoring teams to reduce cognitive load around cloud operations. Unusually, he pairs enterprise-grade security and compliance thinking with a developer-first drive to simplify infrastructure-as-code.
