About

I'm an infrastructure engineer with 14+ years of experience designing and operating cloud systems that stay reliable under real production load. My work spans AWS platform engineering, Kubernetes, and building Infrastructure-as-Code that other engineers can actually reuse — not just scripts that work once.

Currently a Senior/Staff Infrastructure Engineer at NTT DATA, where I focus on Terraform module architecture, CI/CD pipeline design with GitHub Actions and Jenkins, and AWS infrastructure spanning EC2, EKS, RDS, and IAM. Before that, I spent 5 years at JPMorgan Chaseas an SRE, where I learned what "highly available" actually means when real money depends on it.

I'm currently extending that same infrastructure discipline into AI-powered workflows — building agentic tooling and DevOps automation that combines 14 years of hands-on operations knowledge with modern AI engineering practices, rather than treating them as separate disciplines.

Outside of infrastructure, I spend time hiking and exploring off-the-beaten-path places, and I'm a parent navigating the entirely different kind of complexity that comes with that.

Experience

  1. 2022 — Present

    Digital Engineering Sr Staff Engineer · NTT DATA

Projects

Reusable Terraform Module Library

A production-grade module repository covering VPC, EC2, EKS, RDS, Lambda, IAM, Load Balancer, and 10+ other AWS services — built for reuse across multiple environments (dev/staging/prod) rather than one-off scripts.
