With over 4 years of professional experience in development, I have tested software systems to ensure their functionality and performance. By creating and executing testing scripts to thoroughly evaluate the system's capabilities, my diligent approach and attention to detail allowed me to identify and troubleshoot any issues, ensuring the successful launch of the product. Here are a few of my biggest achievements: - Implementing automated integration tests with Cucumber, Selenium and Capybara. - Developed and maintained a booking app using Ruby on Rails, Vue.js, and MySQL. - Developed a machine learning model using Python, auto-sklearn library, Numpy and Pandas to predict tuberculosis patient mortality for a data science internship. - Maintaining an app using Ruby on Rails, Vue.js, and Ionic. - Creating and maintaining microservices built with pure Ruby.
