About me
========

I'm a **problem solver with 20+ years of experience** across
the entire infrastructure stack. **I understand how systems work from
hardware through applications.** I work on complex technical challenges
that require understanding the big picture while debugging the details.
I prefer technical implementation over business presentations.
**I'm looking for Site Reliability Engineer,
Infrastructure Engineer, Platform Engineer, or Software Engineer roles
where I can code regularly and solve complex problems.**

**I operate across infrastructure, systems, and code.** At NTT, I managed
**over 1000 Linux and hundreds of Windows systems, plus complete datacenter
infrastructure across two locations**. Including network, firewall, load
balancers, storage, virtualization, and operating systems. I troubleshoot
from network packets to application code and build automation.
**Whatever it takes to find a solution.**

**I write code to solve operational problems.** I've built Python automation
that reduced backup reporting from hours to minutes and tools that enabled
junior engineers to handle tasks that needed senior engineers. For SUSE's
AWS security competency, I wrote a Fluent Bit output plugin in Go, created
a Helm chart, built CI/CD, and released it as open source. I was
**Contributor and then Maintainer** of `pagure <https://pagure.io/pagure>`_
for 3 years, fixing critical CVEs and shipping releases. Built an OpenShift
operator for AWS Neuron with Red Hat engineers.

**I focus on systems fundamentals and modern infrastructure.** I work with
**Linux**, **Unix / BSD**, **Kubernetes**, **Go**, **Python**, and **C**.
I'm interested in kernel-level work, **Rust**, and **eBPF**. I've earned
**over 70 technical certifications** including **3x Kubernetes**
(CKA, CKAD, CKS), **7x AWS** (e.g. DevOps Engineer Professional),
**18x SUSE**, **5x Red Hat** (e.g. RHCE), and **2x Azure**.
I've shared knowledge at KubeCon, SUSECON, and via blog posts.
