😊 AI-Powered Appointment Booking Automation with n8n
This project is an AI-powered appointment booking automation system built with n8n. The workflow is designed to let a user interact with a conversational AI assistant, request an appointment, provide personal details, and move through the booking process automatically.
The system uses an AI agent connected with a knowledge base, memory, vector storage, and external tools. It can understand user messages, ask follow-up questions, collect booking information such as name and email, check calendar availability, create a calendar event, and send confirmation messages through Gmail. The workflow also includes document ingestion, text extraction, embeddings, and Supabase Vector Store integration so the assistant can answer based on stored business information.
My work focused on building the full automation flow inside n8n, connecting AI models, configuring memory and knowledge base retrieval, integrating Google Calendar and Gmail actions, and testing the conversational booking process from start to finish. The result is a practical AI assistant system that can reduce manual appointment scheduling work and provide a smoother customer booking experience.
Skills & Tools:
n8n, AI Automation, Workflow Automation, AI Agent, Google Calendar API, Gmail Automation, Supabase Vector Store, HuggingFace Embeddings, Google Gemini, Groq, RAG Workflow, Knowledge Base Integration, Chatbot Automation, Appointment Booking System, CRM/Business Process Automation.
GIS-Based Terrain Analysis and DEM Visualization in Sinai
This project is a GIS-based terrain analysis created for the Sinai region using digital elevation model data. The work focuses on extracting and visualizing key topographic characteristics, including aspect direction, hillshade relief, slope variation, and contour elevation patterns.
The project includes four separate thematic maps: aspect analysis, hillshade visualization, slope classification, and contour mapping. Each map was designed with coordinate system information, scale bar, north arrow, legend, and terrain background to support professional cartographic presentation. The outputs help identify terrain direction, elevation behavior, surface steepness, landform structure, and topographic variation across the study area.
My work involved processing DEM data, generating raster-based terrain layers, creating slope and aspect classifications, producing hillshade relief, extracting contour information, styling each map layer, and preparing clean map layouts for presentation. This project demonstrates my ability to handle geospatial raster analysis, terrain modeling, and professional GIS map production.
Skills & Tools:
ArcGIS Pro, QGIS, GIS Mapping, DEM Analysis, Terrain Analysis, Raster Processing, Hillshade Mapping, Slope Analysis, Aspect Analysis, Contour Mapping, Cartography, Coordinate Systems, Spatial Analysis, Map Layout Design, Geospatial Data Visualization.
