Curriculum Vitae

Nap Joseph Calub

Senior Platform Engineer · Philippines (GMT+8) · remote-friendly

Senior platform engineer with 10+ years shipping production systems — the Pipeline-as-a-Service platform that carried every application to production at Penbrothers, student-information features at Oracle, and NOC dashboards for Google as a vendor. I work across Go, TypeScript, and Python with a bias for boring, well-tested infrastructure. After hours I keep building for real users: an agent-authored operating system I run my own workday on, a live-translation stack for my church, and small tools finished properly. This site is the evidence.

Experience

Penbrothers

Nov 2023 – Oct 2025

Senior Platform Engineer · Makati City, Philippines

  • Built and maintained the Pipeline-as-a-Service (PASS) platform — the standardized, self-service route-to-production for every application in the organization, across multiple deployment targets.
  • Shipped the release toolchain product teams used daily: a deployment orchestrator with one-at-a-time production locks and automatic rollback, a GitLab-CI-to-JIRA audit trail, a Flagger canary-plan visualizer, and JIRA workflow diagrams used during the company-wide tooling migration.
  • Owned reliability of the release path: deployments that were timely, compliant, and observable, so product teams shipped faster without a platform engineer in the loop.

  • Built subjects, tags, and grade-management features for Oracle's Higher Education Student Cloud, collaborating with hundreds of developers worldwide (Oracle JET and ADF).
