I build platforms,
not just features.

Senior Systems Engineer by title. Platform engineer, AI architect, and fullstack developer by practice. 20+ years turning infrastructure into systems that think, adapt, and ship. Currently orchestrating 16 AI agents across 19 repositories through a custom ops dashboard.

What I Build

I started in operations — keeping servers alive, managing deployments, watching dashboards at 3 AM. That evolved into infrastructure automation, then into platform engineering, then into building the tools that build the tools.

Today I design interconnected systems where AI agents coordinate development work across an entire ecosystem. 16 specialized agents — each with scoped permissions, custom skills, and independent verification workflows — working in parallel across Python, TypeScript, C++, Go, and C# codebases. A custom ops dashboard tracks 95 backlog items, 15 epics, and 43 security findings.

The portfolio below isn't a collection of hobby projects. It's a self-aware development platform where the agents that build the software also audit, test, and document it. Every devlog entry is written by the agents that did the work.

Professional Experience

Anonymized case studies from enterprise engineering work.

Enterprise Infrastructure

Enterprise Git Migration + CI/CD Modernization

Migrated an entire engineering organization's codebase to a new Git org with GitHub Actions deployment pipelines. Built GitHub Apps integrations, implemented HashiCorp Vault with JWT authentication for secrets management, and integrated Artifactory for artifact storage. Automated dozens of operational processes including certificate provisioning via SecretStore.

LCARS Engineering Dashboard with RAG Chatbot

Built a Star Trek LCARS-inspired GUI system for the engineering team featuring an integrated RAG-indexed codebase chatbot. Engineers search the entire codebase in natural language. Upgraded legacy Windows Forms to modern WPF, integrated with GitHub Actions and Artifactory. The dashboard became the team's primary interface for build monitoring, deployment tracking, and documentation search.
