What I'm looking for

I'm open to QA Engineering and Data Science opportunities within tech startups, fintech, and enterprise environments, both remotely and on-site internationally.

At Hasob Integrated Services Limited, I coordinated testing across sprint cycles and designed test plans that expanded automated test coverage by 75%. My work included tracking defects with JIRA and Plane and reporting QA metrics to the CTO.

I designed automated test scripts with Selenium WebDriver, WebdriverIO, and Katalon Studio, reducing regression testing cycle time by approximately 40%. I also tested backend integrations with Postman and reviewed requirements to surface specification ambiguities early.

As a Data Science Intern at the National Center for Artificial Intelligence and Robotics, I built a CNN-based model to detect and classify breast cancer from histopathological images. I also analyzed supermarket sales data and developed interactive Power BI dashboards.

At Drauig, I developed and maintained machine learning pipelines using Python and scikit-learn. I'm open to QA Engineering and Data Science opportunities in tech startups, fintech, and enterprise environments, remotely or on-site internationally.
