Serene: The Singlish-speaking AI agent automating serverless seafood commerce on WhatsApp

The Fish Farmer Bot, operating under the persona Serene, is a serverless WhatsApp commerce agent designed to automate seafood ordering and customer enquiries using a robust Node.js stack integrated with AWS Lambda, DynamoDB, and OpenAI. The system employs a sophisticated "Intelligent FAQ Waterfall" that prioritises semantic vector search via OpenAI embeddings followed by local fuzzy search to provide accurate information, which is then reframed into Serene's signature Singlish tone using GPT-4o-mini. Beyond dialogue, the bot features a comprehensive shopping engine allowing users to browse a product catalogue through interactive menus or search, manage a persistent cart stored in DynamoDB that survives system cold starts, and navigate a checkout logic that automatically calculates itemised totals and delivery fees. Operational reliability is maintained through message deduplication to prevent infinite loops, "thinking" messages to manage latency, and a data pipeline that performs automated Excel logging of orders and unanswered questions to Amazon S3. Finally, the bot is context-aware, capable of intent detection to switch between professional and casual tones, while also offering a safety trigger that escalates requests to a human agent if the user requires urgent assistance
