As a Full-Stack Developer, I engineered a sophisticated AI-powered support and sales assistant that operates seamlessly across web chat and email channels. This production-ready system combines advanced retrieval-augmented generation (RAG) with real business automation, creating an intelligent assistant that doesn't just answer questions—it takes action, learns from your data, and delivers measurable business results.

Businesses struggle with fragmented customer communication: web visitors need instant responses, email inquiries pile up overnight, support teams get overwhelmed with repetitive questions, and valuable leads are lost due to slow response times. Manual processes for order tracking, meeting scheduling, and lead qualification create bottlenecks that hurt both customer satisfaction and revenue.

I built an omnichannel AI platform that provides consistent, intelligent support whether customers reach out via web chat or email. The system understands context, retrieves accurate information from your knowledge base, and executes real business operations automatically—all while maintaining a natural, helpful conversation.
