Software Tester at PT Multi Guna Gemilang, testing web, mobile, and API functionality with Postman and Playwright.

At PT Multi Guna Gemilang, I test web and mobile applications manually and use Postman to validate API functionality and responses.

I report, track, and verify bugs, and use Playwright for basic web automation. I also use AI-assisted development tools to support code analysis and debugging.

At PT Multi Guna Gemilang, I created technical flow and API documentation from developer code and functional documents, using AI-assisted workflows to help draft documentation.

My earlier work at Lintas Media Danawa included first-level IT support, server and network monitoring, and support for server installations and configurations. I also supported infrastructure maintenance, environment setup, and network configuration at PT Multi Guna Gemilang.
