Processing fees directly impact profitability at scale. If you’re handling 10 million transactions per month with an average transaction value of $100, a 2% effective processing rate results in $2M in monthly fees. Intelligent payment routing can reduce those costs by 30–40%, unlocking $600K–$800K in annual savings, without introducing latency or reliability trade-offs in high-throughput Erlang/Elixir production environments that demand fault tolerance and sub-100ms performan

The velocity of modern payment systems has created an unforgiving paradox: the faster you process transactions, the faster fraud can scale. When you're handling thousands of payments per second across distributed infrastructure, traditional batch fraud detection becomes a liability. By the time you discover fraudulent activity in a daily review, attackers have already extracted value and moved on. For enterprises running high-throughput fintech platforms, especially those bui
