Automated Payment Verification & Tracking System
Overview
Managing payment confirmations manually through Slack can be time-consuming and error-prone, especially when multiple payment screenshots, customer details, and transaction records need to be verified and tracked.
To streamline this process, I built an automated payment verification and tracking system using n8n. The workflow captures payment-related messages from Slack, extracts customer information, processes payment screenshots using OCR, validates transaction details, and automatically updates centralized tracking sheets.
The solution eliminates manual verification efforts and provides a reliable system for tracking payment submissions and status updates.
Key Features
• Real-time Slack payment monitoring
• Automated customer information extraction
• Payment screenshot processing
• OCR-based data extraction
• Transaction validation workflows
• Automated Google Sheets updates
• Duplicate prevention and record tracking
• Centralized payment management
Workflow Architecture
The workflow listens for payment-related Slack messages, extracts relevant customer details, processes uploaded payment screenshots using OCR services, validates transaction data, and automatically updates tracking records. The system also handles file uploads, data merging, and verification logic to maintain accurate payment records.
Tech Stack
• n8n
• Slack API
• OCR Services
• Google Sheets
• JavaScript
• Workflow Automation
Business Impact
• Reduced manual payment verification effort
• Improved payment tracking accuracy
• Faster transaction validation process
• Centralized payment records management
• Increased operational efficiency
What I Learned
This project enhanced my experience in OCR integrations, event-driven workflows, Slack automation, document processing, and building end-to-end business automation systems.

I built City Chemistry for the #ConfigMakeathon 💌🌍
Try it here: https://citychemistry.figma.site/
It’s a compatibility test for the city you can’t stop romanticizing.
City Chemistry asks the less delusional follow-up:
Is that city actually compatible with the life you’re trying to build?
You enter your current city, your dream city, and your lifestyle priorities: budget, weather, social life, career, safety, and future roots.
It gives you a compatibility score, calls out the red flags, finds better matches, and sends you a postcard from future you.
Built with Figma Make, Supabase, Gemini, and Pexels.
This is awesome! Never travelling without consulting “city chemistry” again!
Hi there, delighted to share my entry "World Horizons", just in the nick of time!
It's an Animal Crossing-inspired cozy 3D globe of good news: an antidote to doomscrolling, built directly on World Bank data 🌍
Interact with countries to either test your knowledge or read dialogue designed to teach you about the progress being made, showing how life there is really improving across categories like water, literacy, health and poverty.
And why?
If you read the news or use social media (who doesn't?), you're probably under the misconception that things are in a constant state of getting worse. Inspired by Hans Rosling's "Factfulness", I wanted to make real progress more tangible for adults and kids alike. It's an AI project with a human touch.
Core features
Test mode: guess the trend before the answer reveals.
Learn mode + Almanac: collect each country's good-news story, illustrated with a unique AI postcard for each country.
Put yourself in the game: turn a selfie into your own 3D character that walks the globe.
Extra UI: a torch to light your way in the dark, and a music toggle.
How we built it
Scaffolded with AI coding tools (React + react-three-fiber), then refined the front end in Figma Make. Backend on Supabase, data from the World Bank API.
Character creation chains Grok Vision and Imagine (selfie to stylised drawing) into Meshy (image reference to rigged 3D model).
What's next…
Paywall the custom character creation (Meshy credits cost money), while keeping the globe, data, and learning free for all. And maybe a permanent home on Figma?

This looks really nice, George!
