Hi, I'm Prateek Jain

DevSecOps Architect at Tech Alchemy & Hashirai · CNCF Kubestronaut · Pune, India

I design secure delivery pipelines, Kubernetes platforms, and cloud infrastructure that help teams ship faster without making production fragile. My day-to-day sits across CI/CD, infrastructure as code, observability, supply-chain security, and increasingly, AI-assisted engineering workflows. I write about what I build and break at blog.prateekjain.dev.
