Turns raw bank statement exports into automated financial insights and a grounded Q&A assistant.

• Python
• FastAPI
• Pandas
• React
• RAG

• Engineered a 7-stage Pandas pipeline transforming transaction data into 16 JSON datasets powering 14 dashboard visualizations.
• Implemented salary and recurring-payment detection using statistical scoring across multi-month transaction patterns.
• Designed a retrieval-augmented Q&A system ranking transactions by merchant, category, and recency before grounding LLM responses — cutting context payload 94% (1,500 → 80 rows).

An Android payment flow integrating Razorpay checkout with transaction history and error recovery.

• Kotlin
• Jetpack Compose
• Razorpay SDK
• Material 3

• Integrated the Razorpay Checkout SDK into a Compose payment flow handling 4 distinct SDK-level error states across 500+ test transactions.
