21 Commits • 7 Features
May 1, 2026May 2026 produced a focused set of business- and tech-value improvements around internal communications, authentication, and CI health for the weni-ai/flows repository. The main feature delivered was a FastAPI-based internal WhatsApp broadcast endpoint secured with JWT, integrated with Celery deferment for asynchronous processing, and aligned to Django’s contract with optional TraceForest support. This laid groundwork for scalable internal messaging with consistent payload handling via a JSON-safe Celery flow. Key bug fixes improved reliability and data integrity for organization/user handling and auth behavior. The month also included infrastructure cleanups and stability work to reduce CI noise and future fragility.

Feb 1, 2026February 2026: Delivered analytics and reliability enhancements for weni-ai/flows, adding end-to-end capabilities for data-driven decision making and stable operations. Key features include an Internal Messaging Analytics API for project-level metrics and an Organization-Level Unique Contact Counts Analytics sourced via Elasticsearch, enabling filtered reporting and engagement insights. Upgraded Messaging Infrastructure to AmazonMQ with lazy initialization to improve reliability and throughput, and extended Messaging Analytics to count all messages and unique contact messages for richer reporting. Fixed critical media download routing and error handling issues, and completed infrastructure hygiene with Poetry lockfile and changelog updates for reproducible builds. Overall impact: enhanced business visibility, higher reliability of messaging pipelines, and a more maintainable release process. Technologies/skills demonstrated: Python API design, Elasticsearch integration, AmazonMQ messaging, lazy initialization patterns, Poetry-based dependency management, and release tooling.
