During my time at Spotify

Portfolio project
Allen Tang
During my time at Spotify (2020–2024), I built custom Backstage plugins across several engineering teams within Core Infra. My contributions include:
- Reliability: Built a Service Level Platform to enable teams to define SLIs/SLOs, visualize time-series metrics against SLO targets using RechartsJS, and access executive-level summary stats across all services.
- Observability: Designed and built the Heroic Migration UI, a tool created to track a company-wide metrics migration effort from our in-house time-series database (HeroicDB) to our Prometheus-based databases.
- Storage: Supported a high-priority (P0) initiative by building the GCS Retention Backstage plugin. Partnered with backend storage engineers to design UI workflows that simplified Google Cloud Storage bucket labeling and tracked compliance across the company.
- Fleetshift: Provided frontend consulting (architectural design, mob programming, implementation, and handoff) to build the UI for Fleetshift, an internal tool used for large-scale automated code changes.
