Monthly summary for 2025-10: Across internxt/drive-server-wip and internxt/drive-web, delivered proactive user notifications, security/operational hardening, and performance improvements. Focused on business value by enabling timely, non-spammy alerts, reliable background workflows, secure container images, and streamlined CI/CD, while preserving real-time accuracy in the UI. Key outcomes: - Proactive User Storage Threshold Notifications with centralized checks and efficient data flow - Automated inactivity emails for drive users (daily/day-range cadence) with mail-type migrations and templates - Docker container hardening, immutable files for non-root users, and multi-stage build optimizations for smaller, safer images - Improved email reliability and observability with enhanced error logging and propagation - CI/CD simplifications and production-start reliability improvements - Real-time invite count refresh after invitations in Drive Web

September 2025 monthly summary for internxt/drive-server-wip focusing on performance, onboarding, and payment workflow improvements. Key features delivered: (1) Backend API and performance improvements: removed Rudderstack analytics, increased folders API limit to 1000, increased files API limit to 1000, and optimized file creation with concurrent operations. (2) Onboarding email enhancements for first file upload: added welcome email, tier-based first-upload gating logic, and tests. (3) Payment events and incomplete checkout notifications: added an events module for payment processing, introduced a gateway endpoint to receive events, and migrated incomplete checkout handling to the users module with route fixes. (4) DTO naming consistency fix: complete_checkout_url renamed to completeCheckoutUrl. (5) Reverted isFreeTierUser addition to restore baseline behavior. Major bugs fixed: DTO naming consistency and rollback of isFreeTierUser changes. Overall impact: improved throughput and scalability, reduced complexity from removing analytics integration, smoother onboarding experience, more reliable payment event handling, and improved code quality through naming conventions and safer rollbacks. Technologies/skills demonstrated: Node.js/TypeScript backend, async/concurrency patterns (Promise.all), API gateway routing, event-driven design, migration and refactor discipline, testing, and CI readiness.
