01 — What it was
A comprehensive ERP that brings accounting, human resources and payroll into one system.
02 — Why it mattered
Accounting, HR and payroll share the same staff and financial records, so an error in one carries into the others.
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
QA had to cover the links between modules, for example a change to an employee’s record flowing correctly into payroll and then into accounting, as well as each module on its own.
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
Launched and used in production, bringing accounting, HR and payroll into one system.
08 — What I learned
In an ERP, I learned to follow a single record across modules; most of the risk sits where one module hands data to the next.
