Full-Stack Developer Needed for Small FinTech MVP Improvements

We are building a small fintech MVP and require a full-stack developer to assist with the first version. The platform will allow users to enter transaction details, compare several payment or investment options, and identify the most suitable option based on total cost, fees, and expected returns. The system must calculate the actual cost, including transaction fees and additional charges, and use AI to provide a recommendation. First version scope: - React dashboard - Python / FastAPI backend - SQL database - Transaction and account management - Comparison of several financial providers - Cost, fee, and return calculations - AI recommendation - Basic dashboard with key metrics The financial component must reflect real cost, including all transaction fees and additional charges. The AI component does not need to be complex. An AI API working with the transaction data is sufficient. The primary objective is a useful recommendation based on cost, fees, and expected returns. Experience with React, JavaScript, Python, SQL, and AI APIs is required. Clean architecture and Git discipline are important. The first version must remain small and practical. No large integrations and no over-engineering. A clean, working MVP that provides a foundation for future development. Please send your approach and two or three relevant projects you have worked on.
