PROFILE
Joey Zhou
Over 14 months, contributed to the mozilla/blurts-server repository by building and refining backend systems focused on data integrity, authentication, and deployment reliability. Developed features such as churn management workflows, flexible API endpoints, and robust subscriber synchronization pipelines, leveraging TypeScript, Node.js, and SQL. Enhanced CI/CD automation using GitHub Actions and Docker, introduced Redis-backed session management, and implemented JWT-based authentication with keypair signing. Addressed operational challenges through batch processing, concurrency controls, and comprehensive integration testing. Prioritized maintainability by refactoring code, improving logging, and enforcing access control, resulting in more reliable releases, cleaner data, and scalable infrastructure for ongoing development.

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.
