Mark Murphy

Senior engineer on Nomad, an ad-ops platform for media-buying agencies. I work on the Node/TypeScript API, AWS infra, the Databricks pipelines, and CI/CD.

• Built the notifications system. Central builder feeding queue workers; sends to Jira (ADF format), Slack, and email. Wrote the integration tests and the migration.
• Standardized the dashboard API: typed errors, validation, trace IDs, pagination. Applied it back to deals, campaigns, and customer endpoints.
• Maintain the pacing and billing pipeline. Materialized views for SA360 and Spotify, business-unit-aware QuickBooks invoicing, margin-schedule line items.
• Wrote the Databricks pipeline framework from scratch. ETL and JobStep classes, dynamic resource generation, environment-aware deploys, runtime dep auto-sync.
• Modernized infra across eight repos. Terraform AWS provider upgrades, Lambda 18 → 22 migration, dropped Serverless Framework, S3 lifecycle rules, ongoing vuln triage.
• Ported the API CI/CD from GitHub Actions to GitLab CI with MR-driven dev deploys. Migrated the monorepo to Yarn v4.
• Built a browser-testing tool in Python/Playwright. GUI selector picker, captures Floodlight/network/data-layer activity, ships as PyInstaller bundles via GitHub Actions.
• Moved core data logic out of MySQL triggers into the API layer. Easier to operate, testable in CI.
