May 1, 2025May 2025 (2025-05) focused on delivering foundational features for AWS Bedrock agent integration with Couchbase Vector Search, along with documentation and tutorials modernization. No major bugs fixed this month; emphasis was on building reusable deployment/testing workflows and improving developer experience for Bedrock workflows. Key outcomes include establishing a modular Lambda architecture (separate research and write functions) with API schemas, action groups, and IAM/Couchbase setup to enable agent orchestration. Notebook-based deployment/testing workflow was consolidated for quicker validation and iteration. Documentation and tutorials were updated to ensure compatibility with Couchbase and LangChain, and to provide operational notes for Bedrock agent workflows. Major refactors were completed to improve maintainability and readability of notebooks and the lambda approach. Overall impact: Lays the groundwork for scalable AI agent workflows, reduces deployment risk through tested notebooks, improves onboarding and adoption via updated docs, and strengthens code quality for future enhancements. Technologies/skills demonstrated: AWS Lambda, IAM, API schemas, Couchbase Vector Search, LangChain compatibility, notebook-based deployment/testing, Python scripting, Makefile-driven workflows.
