Co-Founder & CTO The Lobbi Corp
Aug 2025 to present · Remote · alongside TransUnion until Aug 2026
Co-led a three-person team to production beta.
- Wagon Works AI is a Microsoft 365 AI workspace desktop app. The beta progressed from v1.0.0 (Aug 2026) through v1.0.28 to external beta testers.
- 19 reusable composite actions (shared build steps) across a 17-repository fleet: I built the GitHub Actions pipeline factory, with each action pinned to an exact version. The GitHub organization's own settings are kept in Terraform. It cut the release build job from 11 to 14 minutes down to about 3.4.
- Built an OpenTofu CI factory (automated pipeline setup) that provisions pipelines for 10 services across 2 Harness projects (Harness is a build and deployment platform) from one-line entries, with Snyk, gitleaks and SonarQube checks.
- 661 pull requests merged by the team in about 3.5 weeks under the agent-driven delivery model I designed and ran. Coding agents write the code I deliver.
- Automated production credential rotation (replacing access secrets) on a 7-day cadence with one-command rollback (restoring the previous state).
- Led a security review of the app before release.

Software Architect, CI/CD Team TransUnion
Sep 2019 to Aug 2026 · San Luis Obispo, CA
Led an 8-person CI/CD team: the build and release systems for 23 development teams.
- 2024 and 2025: during the manager's extended leave, I ran one-on-ones, performance reviews and sprint planning.
- 80+ applications moved from Docker EE (an enterprise container platform) to Kubernetes, avoiding $1.8M in enterprise license costs. I led the migration ahead of a hard deadline.
- 408 pipelines, 1,000+ repositories and 23 teams: I consolidated three Jenkins instances onto Harness.
- Built a Terraform "Pipeline Factory" for self-service Harness pipelines, and repository settings kept as code, with standard rules and CODEOWNERS (who reviews each part).
- Codified Harness RBAC (who is allowed to do what) for 23 teams in OpenTofu with only the permissions each team needs.
- Implemented Flux CD GitOps deployments (releases driven from Git) for about 40 applications to the company's private cloud.
- Integrated SonarQube, Checkmarx, Sysdig and Wiz scanning into pipelines, and implemented HashiCorp Vault secrets management.
