  • Financial accounting logic — double-entry posting, balance and accrual maintenance, value dating, reconciliation, and month-end close in a regulated environment.
  • Analysis of legacy systems — tracing undocumented logic through copybooks, call chains, and job streams, and stating clearly what a change will and will not affect.
