Project history
Developed scalable backend systems using Java and Spring Boot, building RESTful APIs with 30-40% performance improvement, handling 100K+ records/day, and integrating n8n workflows to reduce manual effort by 60%.
Built and deployed a 24/7 AI voice receptionist handling inbound calls, lead qualification, and appointment booking autonomously. Uses VAPI for voice orchestration, Twilio for call routing, and OpenAI GPT-4 for context-aware responses. Syncs bookings to Google Calendar, pushes leads to CRM via webhooks in real time, and triggers SMS follow-up on missed calls.
Built a 24/7 AI chatbot for VServe Web Solution, deployed via an N8N webhook-powered chat interface. The bot engages website visitors, qualifies leads, captures lead data, appends details to Google Sheets, sends email notifications via Gmail, and uses Groq (LLaMA) as the LLM with PostgreSQL for persistent chat memory and a RAG tool for business-specific answers.
