Abstract Modern financial systems are often described in terms of individual components. Ledgers enforce correctness. Custody systems control asset authority. Compliance systems constrain behavior. Orchestration layers coordinate execution. Each o...

Like many beginner developers, I started with tutorials. I followed along, built small projects, and felt productive. Everything worked… as long as I stayed inside the tutorial. But the moment I tried to build something on my own, I got stuck. T...
