Spills – Monorepo

A full-stack, TypeScript-first implementation of a “round-up” savings feature for bank customers.

This repository contains:

• a React + Vite client
• a secure Express proxy server for the Starling Bank public API
• a full observability stack (logs, traces, metrics)

The backend is designed as a production-style API gateway with strong typing, structured logging, tracing, and token lifecycle management.
