Feb 1, 2026February 2026 monthly summary for jemmia-diamond/fn: Business-value driven delivery focused on data integrity, reliability, and scalable workflows. Key features delivered include lead management hardening (idempotent creation via getOrCreateLead and lead existence validation), promotion processing adjustments (ignore promotion priority order), and expanded order/workflow capabilities (POC endpoint for buyback search, Get order by linked params). Additionally, webhook reliability was significantly improved through an enhanced queue retry mechanism and robust error handling. Architectural refinements include source grouping for call-center, field update optimizations, field renames for consistency, lead-function unification across modules, payload enrichment (pancake info) on updates, and GTM/URL parameter utilities. Major groundwork also laid for data handling with one-time backfill and separation of lead creation concerns. Overall impact: reduced data duplicates, more predictable promotions, resilient integrations, and a cleaner, modular codebase enabling faster future iterations.

Sep 1, 2025September 2025 monthly summary for jemmia-diamond/fn. Focused on reliability, data quality, and maintainability across website, messaging, and tracking domains, with a strong emphasis on delivering business value and scalable frontend/backend capabilities. Highlights include feature rollouts that improve product data presentation and site search, targeted fixes that harden messaging pipelines and data validation, and a cross-service ORM migration to Neon to enable faster iteration and data integrity. Key features delivered: - Website: Added main_stone and stone_quantity to product pages, enabling richer product data display. - Website: Implemented paginated queries for engaged ring listings and added tag-based filtering to improve browse performance and relevancy. - Website: Improved data paths with Return ecom_title, Group by ecom_title, and table/grammar updates; code refactor to reuse existing paths where applicable. - Order-notification: Refactored to reuse number helpers and numberToCurrency for consistent pricing and reduced duplication. - Website Lead: Guarded submissions when phone is undefined or empty to improve data quality. - System readiness: Pre-validation for Zalo tracking and enhanced tracking guards to prevent errors; ERP lead-summaries checks before AI hub dispatch. Major bugs fixed: - Website/messaging reliability: switched to a single async request, reverted Promise.all in tv-service, and separated dequeue logic for message webhook. - Tracking: validated order_id as integer; fixed various tracking status/credentials and WIP-related issues. - Neon ORM migration across modules: migrated temp-product, pancake service, and tracking from Prisma to Neon, enabling unified data access and smoother future migrations. - Zalo/macrost: prevented night-time sends (22:00–06:00) and fixed transfer amount handling with environment/config fixes. - ERP improvements: cleaned up logging and added a guard to check lead summaries before sending to AI hub. - Operational guards: ProcessLastCustomerMessage now ignores processing when not in messaging state; website lead and order notification polish for data integrity and resilience. Overall impact and accomplishments: - Significantly improved reliability of website, messaging, and tracking workflows, reducing failed handshakes and data mismatches. - Enhanced data integrity and presentation, resulting in better customer experience and decision-grade reporting for product listings and orders. - Enabled faster future development through Neon ORM migration, consolidating data access and reducing friction for feature delivery. - Strengthened maintainability through code reuse, cleanup, and guard rails, lowering risk of regressions in production. Technologies/skills demonstrated: - Async/concurrency optimization and robust webhook handling (single async request, dequeue separation). - Data validation and guard rails (integer order_id validation, phone guard on leads). - Data modeling and migrations with Neon ORM across multiple modules. - Frontend/backend refactors for code reuse and query optimization (GROUP BY ecom_title, return ecom_title, tag filtering). - Logging hygiene and operational reliability improvements (ERP logging cleanup, AI hub gating, Zalo environment fixes).
