PROJECT DEEP DIVE

Accounting file automation - BOD/EOD pipeline

Fintech · ASP.NET Core, Hangfire, file integration

Situation

Accounting depended on manual handling of beginning-of-day and end-of-day files that required manual intervention; wrong format, sensitive card data exposed, delivered inconsistently.

What I built

A listener-based ingestion pipeline that picks up the files, runs validation and splitting through Hangfire background jobs, masks card and account-style data, and delivers the transformed output directly to the accounting server in the exact layout finance requires, on schedule, every time.

Result

Finance receives correctly formatted files on schedule with no manual steps. Sensitive payment data is masked before it ever reaches the accounting layer. A process that required daily human intervention now runs unattended.
