About Me

Testing beyond
the happy path.

I am a QA tester with 3 years of experience working on HR and payroll systems. My day-to-day work includes validating API responses, checking business rules, creating structured test coverage, and making sure changes do not introduce unexpected issues in related modules.

I enjoy turning complex requirements into practical test scenarios and helping teams catch issues early before they affect production users.

Projects that reflect
my QA approach

These projects highlight how I validate APIs, analyze workflow impact, and protect system quality through structured testing.

Project 01

Payroll API – Unpost Payroll Feature

Postman SQL JIRA

Validated the payroll unposting flow to ensure finalized payroll entries could safely return to an editable state without affecting downstream data.

  • Covered positive, negative, and edge-case scenarios
  • Verified status rollback and business rule enforcement
  • Checked impact on payslips, payroll tables, and related records
Project 02

Attendance Engine – Schedule Adjustment Integration

Postman SQL JIRA

Tested approved schedule adjustments to confirm they appeared correctly in attendance reports and did not affect unrelated endpoints.

  • Validated single and batch attendance results
  • Confirmed updated schedule labels and report output
  • Performed regression checks on non-impacted APIs
Test Artifacts

Proof of my
QA process

How I write test cases, report bugs, and validate APIs using structured documentation.

Test Cases

Structured scenario design

Samples of BDD-style and functional test cases covering positive, negative, and edge-case behavior.

Bug Reports

Clear defect documentation

Bug reports with reproduction steps, expected vs. actual results, and severity-based communication.

API Validation

Request and response checks

Postman request samples, response body checks, and endpoint validation evidence used during testing.

SQL Verification

Data-level validation

Examples showing how I verify records and confirm system data accuracy after feature execution.

Strengths

How I add value
in QA

Structured test design

I build test coverage around workflows, dependencies, business rules, and real user scenarios — not just the happy path.

Business logic awareness

I pay close attention to how rules, computations, and edge cases affect system behavior, especially in payroll and attendance features.

Clear communication

I document findings clearly so developers and stakeholders can quickly understand the issue, reproduce it, and act on it.
