🧪 Data Alchemist – Smart Data Validator & Rule Engine

🚀 Built with Next.js 15 + AG Grid + Zod + Tailwind
🔧 Role: AI/ML Product Engineer | 🧠 Bonus: Natural-Language Rule Builder (No API Key Needed)

🔍 Overview

Data Alchemist is a no-code web app to clean, validate, and rule-check CSV/XLSX datasets.
It lets users:

• Upload datasets
  
• Highlight and remove invalid rows
  
• Define rules (manually or with text input)
  
• Prioritize rules
  
• Export clean data + rule logic as .csv, .json, or .zip
  

💡 Designed as a technical showcase for SDE, Data, or AI/ML engineering roles.

🎯 Features

✅ Upload .csv / .xlsx files
✅ Schema-based row validation using Zod
✅ Visual data grid using AG Grid v34
✅ Manual rule builder with:

• Rule types: no-collab, must-follow, skill-match
  
• Weight slider (1–10)

✅ Natural Language Rule Generator

• Example: John must follow Alice with priority 8
  
• Generates structured JSON rule without OpenAI

✅ Exports:

• 🧼 clean.csv – valid rows only
  
• 📋 rules.json – all rules with priorities
  
• 📦 bundle.zip – includes both above
  

✅ Legacy AG Grid theming (no Quartz conflict)
✅ Fully offline – no .env or API key needed
