PROFILE

Alex Franchuk

Over several months, contributed to Mozilla projects by building and enhancing crash reporting, telemetry, and data access infrastructure. In mozilla/gecko-dev, improved crash reporting reliability by migrating submissions to the Necko backend and strengthening Windows IPC error handling using C++ and Rust. Updated mozilla/bigquery-etl to streamline access control through YAML-based ACL management, supporting analytics workflows. Integrated the crashping library into mozilla/probe-scraper for standardized cross-platform crash reporting, and added Android OS version retrieval in mozilla/glean to enrich telemetry. Work emphasized robust error handling, configuration management, and system programming, resulting in more reliable data collection and maintainable reporting pipelines.

July 2025 — mozilla/bigquery-etl: Implemented Remote Settings Access Enhancement to grant read access for workgroup 'workgroup:remote-settings/gke' across product configurations. Updated ACLs in multiple metadata YAML files to ensure consistent access across all configurations, enabling broader data accessibility for downstream analytics. No major bugs fixed this month. This work improves data discoverability, governance compliance, and reduces manual data access friction for data consumers. Technologies demonstrated include ACL management, YAML metadata updates, cross-config coordination, and data governance practices.
