March 2025 monthly summary: Delivered the AI RAG Injector Plugin for Kong/docs.konghq.com, enabling data injection from external sources into prompts to enhance LLM applications. The feature includes comprehensive installation, configuration, and usage docs, prerequisites (Redis-Stack), integration with the AI Proxy plugin, and support for multiple embedding models and vector databases, highlighted by an OpenAI+Redis example. All work was anchored by the commit f5652771ef2af8cb9c3f177f7bb65d3fe243b267 (feat: add ai-rag-injector plugin #8607). Documentation updates accompany the feature to facilitate adoption and repeatable deployments. Key business and technical impact: - Accelerates development of AI-powered LLM workflows by enabling RAG-powered prompts through external data sources. - Improves developer experience with end-to-end docs and reproducible examples (Redis-Stack prerequisites, OpenAI+Redis example). - Demonstrates architectural flexibility with multi-embedding model and vector database support and seamless AI Proxy plugin integration. Technologies/skills demonstrated: - AI/LLM tooling and RAG patterns, plugin development, Redis-Stack prerequisites, embeddings and vector databases, cross-plugin integration, and documentation.

December 2024 performance summary focusing on upstream reliability and production stability across Kong/kong and lua-kong-nginx-module. Implemented Lua-driven proxy_next_upstream control, updated dependencies, and a targeted Nginx patch to enable conditional upstream selection based on Lua configurations, significantly improving handling of upstream failures. Introduced a dynamic upstream retry API via resty.kong.upstream.set_next_upstream with associated module/docs/NGINX integration. Also performed a lean production-build improvement by removing an unused debug log in analytics serialization. Regressions were addressed by a CI stability fix reverting the Kong version env back to master. All changes strengthened deployment confidence, reduced upstream downtime risk, and demonstrated solid Lua/Nginx integration, dependency management, and CI hygiene.
