API & Backend Testing

Project: Accelario — Enterprise Data Management Platform
Role: QA Engineer (Manual + API + Backend)
Duration: Ongoing

Scope of Work:
Performed full-cycle API and backend testing to ensure correctness, stability, and reliability of data-driven services that power internal automated workflows.

Responsibilities & Achievements:

Analyzed API architecture, endpoint dependencies, and integration logic

Created and maintained structured Postman Collections grouped by functional modules

Implemented JavaScript assertions in Postman for validation of:

Response structure & payload content

Status codes and error handling logic

Business transformation rules

Conducted MySQL-based backend validation to ensure data consistency across UI, API, and database layers

Performed regression testing of backend workflows before feature releases

Contributed to extending automated test coverage in backend (Java + JUnit)

Example API Test Assertion (Postman, JS):

pm.test("Status code is 200", () => pm.response.to.have.status(200));
pm.test("Response contains non-empty dataset", () => {
const json = pm.response.json();
pm.expect(json.data.length).to.be.above(0);
});

Tools & Tech Stack:
Postman, JavaScript (Assertions), MySQL Workbench, Git, Java, JUnit, Jira

Result:
Improved backend issue detection at early stages, increased API test coverage, and reduced regression defects affecting production data pipelines.
