What I'm looking for

I'm seeking a UK-based SRE role (remote/hybrid) to lead infrastructure modernization, apply AI-driven incident automation, optimize cloud costs, and mentor distributed engineering teams.

I am a Senior Site Reliability Engineer with 5+ years of experience leading infrastructure modernization and operational excellence across international teams. I transitioned to UK-based remote work while maintaining technical leadership across US and Indian engineering organizations.

I have led large migrations, including moving 35+ applications to Kubernetes with 1000+ nodes and designing a self-hosted monitoring stack handling over 20 million active time series. I built AI-powered incident management using the Claude SDK and MCP servers that reduced manual incident response by 60%.

My hands-on expertise spans AWS (EKS, EC2, S3, Lambda, Graviton), containerization (Docker, Kubernetes, Buildx), and IaC (Terraform, CloudFormation, Helmfile), delivering measurable cost and performance improvements such as a 40% infrastructure cost reduction from Graviton migrations and 95% container image size reduction.

I enjoy automating complex workflows, improving reliability, and mentoring distributed teams to maintain high availability (99.9% uptime). I am seeking UK-based SRE opportunities where I can drive infrastructure optimization, AI-enabled automation, and scalable platform improvements in hybrid or remote settings.
