AI-Powered Expense & Inventory Tracker via Telegram
Built a Telegram bot that turns natural-language messages into structured financial and inventory records. A user sends something like "spent 5 on bread" or "sold 5 bags of coffee," and the bot uses Claude's API to classify the message and log it automatically to Google Sheets — no forms, no manual entry.
The system serves two purposes at once: personal expense tracking, and inventory/sales management for a small family coffee business, where stock levels update in real time as sales are logged.
Built solo, end-to-end: bot logic, AI classification pipeline, and Google Sheets integration.
🚀 Turning Manual E-commerce Order Processing into an Automated Workflow with n8n
Manual order management may seem simple, but copying customer details, checking information, preventing duplicate orders, and sending confirmation emails can quickly become repetitive and error-prone.
I recently built an end-to-end order processing automation using n8n to solve these challenges for a handmade products store.
Here's what I implemented:
🔹 Automated Order Capture: Receive new orders through a webhook.
🔹 Data Validation & Cleaning: Validate required fields, email formats, quantities, and prices before processing.
🔹 Duplicate Prevention: Detect existing Order IDs to prevent duplicate records.
🔹 Google Sheets Integration: Automatically store valid orders and calculate order totals.
🔹 Email Notifications: Send order updates to the store owner and confirmation emails to customers.
🔹 Error Monitoring: Capture failed executions, log error details in a dedicated Google Sheets tab, and send email alerts.
The goal was simple: reduce repetitive administrative work, improve data accuracy, and make order operations more reliable.
This is what I enjoy about building with n8n — turning complex, repetitive business processes into practical automation systems.
