Aspiring QA Engineer

Hi, I’m Sacar Shrestha

Motivated and detail-oriented aspiring QA Engineer with a growing focus on software quality assurance. I have hands-on experience with API testing, SQL-based backend data validation, debugging, and frontend validation. I’m familiar with writing test cases, identifying and reporting defects, and performing functional and UI testing. I’m a proactive learner who is eager to improve QA skills through hands-on work and guidance from experienced team members.

What I Do

API Testing

Test REST APIs for the kataho.app platform and internal projects using Postman and Newman, validating authentication flows, status codes, response structures, assertions, and API chaining and edge-case handling in development environments before release.

Functional & UI Testing

Perform functional and UI testing on Kataho and insurance workflows, covering core user journeys, form validations, business logic checks, and error handling to ensure smooth user experience.

Database Validation

Perform SQL/MySQL queries to verify backend data integrity, business rules, and consistency between API responses and stored records.

Load Testing

Use k6 to simulate traffic and evaluate API performance, response time, and system stability under load.

Bug Reporting & Jira Collaboration

Log and track defects in Jira with clear reproduction steps, priority classification, and expected vs actual results. Collaborate with developers to retest fixes and verify issue resolution.

Test Automation (Playwright)

Write basic end-to-end test scripts using Playwright, including element locators, assertions, and form validation checks to simulate real user interactions.
