Internal tax filing tool for HLB HAMT

What it ran on before

HLB HAMT, a large tax consulting firm, running client filings on spreadsheets with sensitive data moving over email and no audit trail.

What was built

An internal web application deployed inside their protected network, with role-based access, an audit trail, and email sent through Microsoft Graph rather than SMTP because the app handles confidential client information.

Why it is described and not measured

There is no percentage on this page, and there is not going to be one. This build was never instrumented against a baseline, so any figure I published would be a guess dressed up as a result. What is here is what exists and what it does.
