You will get chatAI – AI Appointment Scheduling Platform
Rising Talent
Project details
I build production-ready AI chatbots that handle real conversations, extract structured data, and automate business workflows.
My recent project — chatAI — is a production-deployed bilingual appointment booking system powered by GPT-4.1 with dual NLU-NLG architecture. This is the type of system I build for clients.
The chatbot guides users through a natural conversation and automatically extracts all 5 required booking fields: name, service, phone number, date, and time — no forms, no clicks, just conversation.
What makes my work different:
— Systems that run in production, not just demos
— Dual NLU-NLG architecture for precision + natural conversation
— FastAPI backend with PostgreSQL and JWT authentication
— WhatsApp automation with crash-recovery reminders
— Clean, documented, deployable code
I deliver on time, communicate clearly, and fix issues fast.

About Elvira
FullStack AI Engineer | LLM & Local RAG Specialist | FastAPI & Node.js
Chisinau, Moldova - 12:55 am local time
Whether you need a 100% private, offline AI solution running locally or a highly scalable, multi-tenant cloud application, I architect end-to-end architectures that drive real business results.
WHAT I DELIVER:
• Intelligent Local RAG Systems: Secure, offline document processing using Ollama (Llama 3 & nomic-embed-text), featuring advanced sliding-window chunking and fast context-retrieval pipelines.
• Autonomous Conversational Agents: Multi-turn bots (Telegram, WhatsApp, Web) with automatic language detection, intent routing, and real-time lead qualification scoring.
• Advanced Backends & Automation: Highly optimized APIs built with FastAPI (Python) or Express (Node.js) integrated with PostgreSQL, vector storages, and automated tools like SendGrid.
• Modern Interactive UIs: Lightning-fast frontends built with React and Vite, seamlessly deployed and connected to cloud environments (Render, Vercel).
OUR FLAGSHIP ECOSYSTEM MODULES:
1. chatAI RAG Q&A — A full-stack solution processing local files, generating high-accuracy embeddings, and delivering secure conversational insights without cloud leaks.
2. chatAI Appointment & Lead Bot — An intelligent multi-turn scheduling platform that automates customer communication, qualifies potential leads (Hot/Warm/Cold), and triggers automated follow-up emails.
I focus on turning complex technical requirements into clean, maintainable, and well-documented code that serves actual business workflows. Detail-oriented, fast learner, and fluent in professional English communication.
