Mar 1, 2025March 2025 highlights for mozilla/blurts-server: Local development enablement, Moscary auth groundwork, and careful auth experimentation with rollback to preserve stability. Delivered local backend support with adjusted API URL construction and extensive console logging to accelerate local testing. Initiated Moscary authentication integration including env var, JWT generation/exposure in session, Redis-backed storage, key namespace improvements, and feature flag controls. Explored FXA token authentication for OneRep API calls; implemented and rolled back to maintain existing authentication flow. Result: stronger local dev velocity, scalable authentication foundation, and improved observability.

Jan 1, 2025January 2025: Delivered churn-management features and infrastructure improvements for mozilla/blurts-server, including new churn email data model and state management, churn coupon scheduling and dispatch via cron jobs, admin UI and data ops for churn subscribers, batch/infrastructure improvements with TS migration and lint/log enhancements, and a new reactivate endpoint wrapper with reactivation flow in renewal. Addressed critical stability issues through major bug fixes (date handling, removal of stray console logs, lint cleanup, database/type fixes for subscriber churns, removal of BigQuery usage and improvements to churn data retrieval and header validation, admin checks and environment variable cleanup). These efforts reduce churn cycle times, automate retention communications, improve data hygiene, and strengthen operational governance with stronger tests and better observability. Technologies/skills demonstrated include TypeScript migration, cron-based automation, Knex migrations, TS/packaging improvements, and backend-UI integration.
