Rockstar🎓
Top SchoolJohn Scancella is a Principal Engineer and BPDO Liaison with 11+ years of experience modernizing mission-critical government systems and driving enterprise-wide DevOps and observability adoption. He has led the USPTO’s first continuous deployment pipeline, delivered major cloud migrations that retired legacy COBOL systems, and cut MTTR from days to under 30 minutes while saving millions through open-source tooling and automation. Equally comfortable in Java, Groovy, and build/tooling ecosystems (Gradle, Jenkins, Terraform), he champions resilience engineering, semantic versioning, and contract testing to improve reliability and reuse. At the Library of Congress he co-authored an internet standard (BagIt v1.0) and rebuilt core tools to raise test coverage and remove thousands of LOC, demonstrating both standards-level impact and hands-on refactoring skill. An active contributor to open-source documentation (SpotBugs), he combines technical writing with engineering to clarify intent for static analysis and developer onboarding. Based in Manassas, VA, he pairs strategic leadership with pragmatic delivery, accelerating teams from legacy inertia to continuous delivery.
