Senior infrastructure engineer with 10+ years building and operating production systems at scale — from architecture and IaC through observability, incident response, and mentoring across remote, globally distributed teams. I work the whole delivery path (application code → the pipelines that ship it → the infrastructure it runs on) with a security-first eye, and I like finding the sharp edge in a system and fixing it at the root.

• Modernizing legacy workloads into Dockerized services on Kubernetes / AWS EKS; Kubernetes in production since 2022.
• Read source, not just docs — Kubernetes kubelet security research (subPath traversal, authorization bypass, ImageVolume, Pod resource consistency).
• Currently: modernizing kubernetes-zfs-provisioner together with its maintainer, and hunting reproducible bugs across CI/CD toolchains.

I fix real, reproducible bugs in the tools I run in production. Every patch starts from a failing reproduction and lands with a regression test and a root-cause writeup; the bug classes repeat across ecosystems, so the method carries across Go, PHP, Python and JS.

29 merged upstream pull requests across 14 projects — Kubernetes autoscaler, Argo Workflows & Argo CD, Symfony, Ansible, Spinnaker, goreleaser, Laravel, sigstore/cosign, PHP-CS-Fixer, iTerm2 and others → all merged PRs

• Security fix released in Symfony v8.1.4 — hardened the weak-secret guard in Uuid47Transformer for secrets longer than 16 bytes (#65105, release notes), one of four merged Symfony fixes
• Kubernetes autoscaler/addon-resizer — eliminated its reachable CVEs, fixed go vet, and gave the subproject its first CI workflow (#10112-#10114)
• kubernetes-zfs-provisioner — modernizing it together with the maintainer: leader election moved to coordination Leases, the SSH shell wrappers replaced with a native Go SSH runner, and provisioning made production-safe with in-process volume expansion (5 merged PRs and counting)
• Argo — fixed a ParseProgress panic in Workflows including the release-branch backports (#16537), and surfaced the Suspended condition for suspended Jobs in Argo CD (#28738)
• Supply chain / release tooling — checksum validation of the TUF root of trust in cosign initialize rejected valid uppercase digests (#5036); unanchored goarm64 validation in goreleaser (#6727)
