AI Sales Agent
The bilingual AI agent on this very site — it knows my real work through RAG, captures leads, books meetings and remembers returning visitors.
The problem
A landing page that only lists services is passive. I wanted a site that actively talks to visitors, answers accurately about my work, and turns interest into captured leads and booked calls — without me in the loop.
Architecture
A static Next.js front end calls a Node/Express backend on AWS Lambda. The agent runs on gpt-4o-mini with retrieval-augmented generation (text-embedding-3-small over my real content) for grounding, OpenAI function-calling tools for real actions (lead capture + Amazon SES email, Cal.com meeting booking, live GitHub lookup), and per-visitor long-term memory in DynamoDB. API keys stay server-side and every layer degrades gracefully.
Result
A bilingual agent that answers from real data instead of hallucinating, emails leads and meeting confirmations automatically, and recognizes returning visitors — built and shipped to production in phases.
