Projects
Self-Hosted AI Calling Infrastructure (LiveKit + Twilio)
An AI voice caller system using LiveKit and Twilio enables automated outbound calls with real-time, natural conversations. It integrates ElevenLabs for text-to-speech, Deepgram for speech-to-text, and OpenAI GPT-4o for conversational intelligence. The platform automates lead qualification and onboarding, stores call transcripts and metadata in MongoDB, supports real-time webhooks and SMS, listens to Calendly events, and securely uploads call recordings to Google Cloud Storage. It is designed to be scalable, low-latency, and fully self-hosted.
AI Customer Support Chatbot
An intelligent e-commerce customer support system provides real-time assistance for order inquiries and product information through a conversational interface. Users can check order status, track shipments, and browse product categories seamlessly. A Next.js frontend delivers a responsive chat experience with persistent session management, while a Flask backend securely handles API requests with input sanitization and CORS protection. The system integrates with Saleor’s GraphQL API to retrieve detailed order data, including customer details, line items, addresses, and fulfillment tracking. OpenAI GPT-4o-mini powers the conversational AI with function calling, MongoDB stores chat history using UUID sessions, and Langfuse enables observability and performance monitoring.
MySQL to PostgreSQL E-commerce Migration Tool
A comprehensive ETL (Extract, Transform, Load) system that migrates complete e-commerce data from WSM (Web Store Manager) to Saleor platform. The tool handles products, categories, customers, orders, inventory, and media assets using multi-threaded processing with batch operations. Features real-time progress tracking, incremental migration capabilities, and robust error handling for large-scale platform transitions.
Automated Local SEO Content Generation System (n8n)
Automated SEO content generation system creates location-specific service pages for local businesses. The workflow analyzes competitor search results, extracts geographic data, and generates optimized content using AI. It processes business keywords and locations, performs SERP analysis to identify competitors, scrapes competitor websites for content gaps, and uses AI models to create SEO-friendly titles, meta descriptions, and full content. The system integrates multiple APIs for geolocation, search analysis, and content generation, delivering comprehensive local SEO content through a webhook-based architecture.
