Petar Stanisic

Successfully transitioned from QA to a developer role, contributing to four different applications by implementing new features, fixing bugs, and ensuring app stability. Gained hands-on experience with UIKit, MessageKit, CoreData, Combine, CallKit, push notifications, and many more. Managed the Apple Developer Portal, overseeing TestFlight and App Store releases. Collaborated with teams of up to seven developers across multiple locations and multinational offices, while also guiding management and designers on Apple guidelines and potential challenges. During this period, I worked on applications focused on chat and VoIP calls, enhancing real-time communication features and ensuring seamless user experiences

As an Automation QA Engineer across two teams, Meetings and Coligo, I played a key role in the development of web and mobile applications for business users, specializing in conference calls, group chat, and a Viber-like app for iOS and Android. My responsibilities included researching automation tools, designing and implementing test automation frameworks from scratch (NightWatchJS, later Cypress.io, and Appium with Java using the Page Object Model pattern), collaborating with developers on JavaScript unit tests, performing daily exploratory testing, assisting designers and stakeholders, and submitting bi-weekly reports to the QA Manager.
