Who Am I

Experienced QA Engineer in mobile and web applications. Specialized in functional, integration, UI, and API testing. Proficient with tools such as Postman, SoapUI, Appium, Selenium, JUnit, Jira, Trello, and TestFlight, focusing on optimizing testing workflows and enhancing product quality.

Analyze Requirements

My first step in the QA process is to deeply understand the project requirements and acceptance criteria. This ensures that I know exactly what needs to be tested, which use cases are critical, and how the product is expected to behave for end-users.

Plan & Design Tests

I create detailed test scenarios and test cases covering functional, integration, UI, and API layers. My focus is on building clear, maintainable test documentation that guides the entire testing cycle and ensures no critical feature is left unchecked.

Execute & Automate

Using tools like Postman, SoapUI, Appium, and Selenium, I execute manual and automated tests. This step validates core functionality, user interactions, and backend services, ensuring the product works reliably across different environments and devices.

Report & Improve

I log issues with precision and collaborate closely with developers and product teams to resolve them. My goal is not only to find bugs but also to improve the overall quality, usability, and stability of the product before it reaches users.

What am I doing

I am ensuring the quality of mobile and web applications through comprehensive testing processes.

Functional & UI Testing

I validate that applications work as intended by performing detailed functional and UI tests. This ensures that every feature delivers a seamless and user-friendly experience.

Integration & API Testing

I test integrations between systems and verify APIs using tools like Postman and SoapUI. My focus is on ensuring stable and reliable communication across all services.

Mobile & Web Testing

I perform tests on mobile (iOS & Android) and web platforms using frameworks such as Appium and Selenium. This guarantees cross-platform consistency and performance.

Reporting & Quality Assurance

I document test results, track issues in Jira or Trello, and collaborate with teams to resolve them. My goal is to improve product quality and deliver reliable, bug-free applications.
