I launched Aura Finance, an AI‑powered personal finance assistant that blends traditional analytics with generative AI to let users ask natural‑language questions about their spending while keeping all monetary calculations under strict backend control.
I separated all financial calculations from the LLM, using Python's Decimal type for precise monetary arithmetic.
I built a FastAPI backend that produces verified financial facts which are then passed to Google Gemini for natural‑language explanations.
I implemented monitoring of AI latency, token usage, and estimated API costs, logging each request in the usage ledger.
