I developed a robust automation framework using TypeScript and Mocha to run 2–4 parallel drivers for real-time multiplayer game testing. I also integrated tools such as Appium, LambdaTest, Jenkins, and the Slack API for seamless test execution, reporting, and collaboration. This framework improved test coverage, speed, and reliability for Zupee’s gaming platform.

At Zupee, recurring test failures were caused by reusing whitelisted phone numbers with prefixed OTPs across multiple environments.

This often led to forced logouts during test runs, resulting in failed builds and inconsistent automation results.

To address this, I developed a smart number management system using MongoDB to handle test numbers dynamically and securely.

Numbers were stored with custom properties (e.g., game type, environment), allowing tests to query and select the appropriate number as needed.

A locking mechanism was implemented to ensure that once a number is picked, it cannot be reused by any other test until the current test completes.

This lock was maintained regardless of whether the test passed or failed midway, ensuring complete isolation.

The system integrated seamlessly with the automation framework, requiring only the property input from the test to fetch and lock a number.

As a result, test flakiness was significantly reduced, builds became more stable, and debugging number-related issues became easier and more transparent.

Unikwik_App is a mobile-first platform designed to simplify the university application process for students worldwide. Built using Flutter, the app offers a smooth, responsive experience on both Android and iOS devices. Key features include:

• University discovery: Filterable listings by country, program, and eligibility.

• Real-time interaction: In-app messaging and “Ask a Question” features for student-counselor communication.

• Profile management: Students can manage their profiles, academic data, and preferences.

• Smart UI: Focus on clean, intuitive navigation and modern visual design using custom widgets and Glassmorphism.

As the sole developer, I led the design, development, and testing lifecycle, integrating Firebase for authentication and back-end services. The app aims to eliminate manual counseling bottlenecks and offer a self-service model for faster decision-making.

MY ROLE
I designed and implemented a robust automated testing framework using JavaScript, Mocha, and WebDriverIO. My work included building reusable page objects, validating core functionalities, and ensuring seamless integration across critical modules. I also integrated Allure Reports for clear visibility of test execution. I aligned QA efforts with CI/CD pipelines to provide stability and fast feedback in a fast-paced agile environment.

I worked as a QA automation engineer on a short-term project for DataVisyn GmbH, an Austrian company specializing in biomedical data visualization platforms. I built and enhanced Playwright-based automated tests for highly interactive scientific dashboards in pharmaceutical research and clinical trials.

My work validated data-driven visualizations, including hexbin plots, interactive charts, and multidimensional filters. I implemented reusable Page Object components and integrated screenshot-based visual verification to ensure consistency in rendering across browsers. The framework followed a BDD structure using Cucumber for collaborative scenario writing and clear test documentation.

I collaborated closely with a distributed team of developers and data scientists to align automation coverage with product requirements, contributing to faster and more reliable UI releases.
