Introduction

Every developer has that one project that started with excitement but stalled before completion. For me, it was XMLPayments — a prototype designed to orchestrate XML-based financial flows. The GitHub Finish‑Up‑A‑Thon Challenge gave me the push I needed to finally polish it up, and GitHub Copilot became my silent co‑developer.

This is the story of how XMLPayments went from legacy fragments to a live orchestration engine.

The original XMLPayments repo was functional but fragile:

Fragmented XML flows with no orchestration.
