Overview
MoneyCheck converts a spending scenario into budget impact, opportunity cost, risk, future-value impact and a plain-language explanation.
Problem
A purchase price rarely explains the full decision. People may need to understand how it affects their budget, savings goals and alternatives without working through every calculation themselves.
What I built
- Authentication and database-backed decision history.
- Structured records for spending scenarios and calculated outputs.
- API integrations and AI-generated explanations grounded in the calculated data.
- A dashboard and exportable records.
Engineering decisions
I kept deterministic calculations separate from the AI explanation. The model explains structured results instead of inventing the financial analysis, making the output easier to reason about and audit.
What I learned
MoneyCheck taught me to treat AI as one part of a product workflow. Clear inputs, structured calculations, persistence and understandable failure states matter as much as the generated response.
