FinanceAI – AI-Powered Personal Finance & Expense Tracker
Overview
FinanceAI is a modern full-stack web application designed to help users manage their personal finances more effectively using AI. It combines real-time expense tracking with intelligent financial insights powered by Google’s Gemini 3 Flash model.
Problem
Most expense tracking tools only record transactions but fail to provide actionable insights. Users often struggle to understand their spending behavior and improve their financial habits.
Solution
FinanceAI solves this by integrating AI directly into the financial workflow. The system analyzes user spending patterns and generates personalized insights, budget recommendations, and savings strategies in real time.
Key Features
AI Financial Insights: Generates smart recommendations based on user data
Expense Tracking: Categorized tracking across multiple spending types
Interactive Dashboard: Visual breakdown of expenses using charts
Smart Budgeting: Monthly budget control with overspending alerts
Secure Authentication: JWT-based login with protected sessions
Modern UI/UX: Smooth animations and responsive design
Tech Stack
Frontend: Next.js, React, TypeScript
Backend: Next.js API Routes (serverless architecture)
Database: MongoDB with Mongoose
Authentication: NextAuth.js (JWT, bcryptjs)
AI Integration: Google Gemini 3 Flash API
Visualization: Recharts
Styling & Animation: Tailwind CSS, GSAP
My Role
Designed and developed the full-stack architecture
Integrated AI for real-time financial analysis
Built responsive UI with modern animations
Implemented secure authentication and API structure
Optimized performance and data flow
Outcome
FinanceAI demonstrates how AI can enhance traditional financial tools by transforming raw expense data into meaningful, actionable insights. It highlights my ability to build scalable, AI-driven applications with a strong focus on user experience and clean architecture.

🚀 Excited to share my latest project: AI-Powered Resume Analyzer & ATS Optimizer. I built a full-stack, AI-driven SaaS application that helps users analyze and improve their resumes based on ATS (Applicant Tracking System) standards.
💡 The idea was simple:
Most resumes fail not because of skills, but because they are not ATS-friendly.
So I built a platform that not only scores resumes but also improves them intelligently using AI.
🔍 Key Features:
• AI-powered ATS scoring (0–100) with detailed section-wise breakdown
• Smart AI suggestions to rewrite weak content using professional language
• Side-by-side comparison (original vs. improved) with one-click copy
• PDF & DOCX resume parsing with cloud storage
• Modern SaaS dashboard with dark/light mode and smooth UI interactions
• Secure Google authentication with full history tracking
⚙️ Tech Stack:
Next.js, TypeScript, Tailwind CSS, Shadcn UI, MongoDB, Mongoose, NextAuth, UploadThing, Google Gemini AI
🎯 What I focused on:
Clean and scalable architecture
Real-world SaaS UI/UX (inspired by Vercel & Stripe)
Performance optimization and smooth user experience
AI integration for practical use cases (not just demo)
This project helped me deepen my understanding of:
👉 AI integration in real applications
👉 Building production-ready SaaS products
👉 Designing modern dashboards with great UX
