Over four months, Adam Komarzewski enhanced data analytics and governance across several Mozilla repositories. He expanded the mozilla/looker-spoke-default Looker models by exposing granular event dimensions and later improved BI stability by hiding deprecated explores, using LookML and SQL for robust data modeling. In mozilla/gcp-ingestion, Adam updated scrubbing rules to strengthen data privacy and quality, leveraging Java and YAML for precise data ingestion and processing. He also implemented automated data retention for iOS fx-accounts in mozilla/probe-scraper, aligning with privacy requirements through configuration management. Adam’s work demonstrated thoughtful engineering depth, balancing feature delivery, compliance, and long-term maintainability.

For 2025-10, the focus was stability, governance, and preserving BI assets in the Looker models for mozilla/looker-spoke-default. Delivered a targeted feature to hide the funnel_analysis explore due to reliance on unmaintained tables and low usage, which prevents new discovery from outdated surfaces and protects existing dashboards and looks. The change was implemented with a clear commit (DENG-9951): 3b0df6d88a2acf2ef57e20b3ebbca281dd904576. This work reduces maintenance risk, simplifies discovery, and preserves business analytics assets without impacting current user workflows.

In March 2025, I focused on strengthening data quality and privacy in the mozilla/gcp-ingestion ingestion pipeline. I delivered a targeted bug fix that updates the Telemetry Data Ingestion Scrubbing Rules (IGNORED_TELEMETRY_DOCTYPES) to scrub additional sources, preventing ingestion of unwanted data and improving overall data quality and privacy. The change was implemented via two commits tied to Bug 1955662 and Bug 1955660, demonstrating precise traceability and alignment with stakeholder expectations. This work reduces noisy data, enhances analytics accuracy, and supports compliance requirements while maintaining a lean, auditable ingestion pipeline.

December 2024 — mozilla/looker-spoke-default: Delivered a key analytics feature that enhances Accounts data stream granularity and reporting capabilities. Implemented exposure of additional event extras as dimensions by extending the Events data surface (events_stream_with_extras) in the Explore/View layer, enabling finer-grained analysis for product, marketing, and growth initiatives.
