Context & problem
Customer requirements and administrative documents need consistent workflows, access control, and records. This example uses an internal portal without disclosing company or customer data.
Contribution & solution
Development of CRM, invoices with PDF, employee-linked payroll slips, and accounting modules. Amounts are calculated on the server and key changes are audited.
Implementation
Modules extend the existing Laravel and Blade application. Long documents, duplication, access control, and accounting consistency are covered by local tests.
Verifiable result
Source implements document workflows from entry through printing and recording. Local baseline on 19 October 2026: 140 tests and 1,209 assertions passed. This is local software verification, without implying measured customer business outcomes.
Measurement limits & similar work
No time savings, revenue, or conversion uplift is claimed. Similar implementations need their own role mapping, document formats, business rules, and acceptance criteria.
Evidence & verification limits
An internal system example. No customer names, transaction records, or testimonials are used. Local technical evidence does not replace operational acceptance testing.
