Contributions

  • Owned the public API across 60+ tagged releases, with a layered test suite spanning unit, integration and end-to-end runs against a docker-compose grid.
  • Cut p95 latency by roughly 3x through schema normalization, targeted indexes and materialized-view caching on hot resource-aggregation endpoints.
  • Built the concurrent indexers — Go generics, goroutine pools — that aggregate state from 3,000+ edge nodes into the query layer in near real time.
  • Exposed filtering, sorting and pagination over heterogeneous resources.
  • Built a data-dump generator that seeds production-scale datasets so benchmarks and integration tests catch regressions before deploy.
