Overview
Direct deposits are a major driver of account growth and profitability — but switching them to a new financial services provider is a hassle for employees and providers alike. The experience is high-friction, dated, and prone to manual errors and fraud.
Atomic's connector platform automates that switch. My work focused on building and maintaining the JavaScript connectors that interface with payroll providers, plus the real-time monitoring layer that surfaces breakage before it costs conversion.
