01 — What it was
A system for auditing and reconciling revenue streams, used by the General Auditing Commission of Liberia.
02 — Why it mattered
It supports transparency and accountability in financial reporting.
03 — My role
Senior QA Engineer | Systems Implementation Engineer at Devnest Systems, as part of the delivery team. I didn’t build the system.
04 — Technical problems
Reconciliation has to be exact, so QA had to check that figures from different revenue streams were matched and reported correctly.
05 — What I did
As part of the Devnest team, I ran Playwright regression suites, supported data migration with Postman and Microsoft SQL Server, took part in production deployments, and trained and supported end users through documentation and remote troubleshooting.
06 — Tools
Playwright, Postman, Microsoft SQL Server
07 — Result
In use by the General Auditing Commission of Liberia.
08 — What I learned
An audit tool has to be auditable itself: I learned to check not just that totals match, but that someone reviewing them can see how they were reached.
