AI Chatbot

RAG AI Knowledge Base & Document Chatbot

Built an end-to-end Retrieval-Augmented Generation (RAG) system in Python for querying a private document knowledge base. The system ingests structured Markdown documents, splits them into meaningful semantic chunks by heading, paragraph, list, table and code block, and converts each chunk into a 384-dimensional embedding stored in Qdrant with its source file, chunk number and heading path. A user's question is embedded and matched against the closest chunks, which are passed to a local Ollama/Gemma LLM to generate a grounded answer — with source transparency and multi-turn conversation history.

AI Project Management

TaskFlow AI

TaskFlow AI combines traditional project management with a conversational AI assistant, real-time voice interaction, and a RAG-powered knowledge base. Users manage projects and tasks through the interface, or simply ask in natural language or by voice — the AI converts requests into real actions through function calling, with confirmation on anything critical and a full activity log. Teams can also upload project documents and ask the AI questions about them, with answers backed by cited sources. Built with React, Node.js, Express, MongoDB and OpenAI GPT-4o.

AI Automation

AI Email Assistant

An AI-powered email automation workflow built with n8n, OpenAI, Gmail, Google Calendar, Slack and MongoDB. It watches a Gmail inbox, analyzes each message with OpenAI to classify its category and priority, drafts a reply, and detects meeting requests to create Google Calendar events automatically. High-priority emails are routed to Slack for human approval before anything sends, Gmail labels are applied automatically, and every processed email is logged to MongoDB for a full audit trail.
