Location Tech Internal Data Downloader
Secure, role-based export interface abstracting enterprise data warehouses
An internal data export application providing controlled, filter-driven access to geospatial BigQuery datasets, supporting both dummy sandbox and production data downloads with fine-grained role authentication.
Challenge & Bottlenecks
Operational teams and non-technical stakeholders needed direct access to specific slices of location data without querying BigQuery directly or risking unmonitored warehouse execution costs.
Architecture & Strategy
Built a secure internal portal that abstracts complex BigQuery SQL pipelines behind an intuitive filter interface, enforcing query rate-limiting, role-based permissions, and asynchronous batch file generation.
How The System Operates
Authenticated Access
Internal users log in using verified corporate credentials with assigned data permissions.
Filter & Target Selection
User selects desired dataset mode (Dummy Test Data vs. Production Real Data), date ranges, and geographic filters.
Asynchronous Query Processing
Backend compiles parameterized extraction requests and triggers optimized backend queries.
Controlled File Download
Generated dataset files are packaged into secure downloadable archives with access audit logging.
Key Technical Highlights
- •Safeguarded enterprise data warehouse against unbounded ad-hoc queries
- •Dual-mode toggle between synthesized test fixtures and production data slices
- •Granular audit trails tracking who exported which dataset and when
