Tidder JailZwei

As a Principal Android Engineer at Opitas Inc, I have successfully built a Rubik's cube solving app that has garnered over 1 million downloads and maintains a 4.6 rating. My expertise in integrating C++ code using NDK has allowed me to enhance app functionality while also addressing bugs and implementing new features for the iOS version. My commitment to delivering high-quality applications is evident in my work, where I prioritize user experience and performance.

Previously, as a Senior Android Engineer at Spotify, I played a pivotal role in the development of the main music app, which serves over 200 million users daily. My leadership in creating new ad formats contributed to an impressive increase in revenue by over $80 million annually. I collaborated closely with cross-functional teams to ensure timely releases and built dashboards using SQL to monitor app features and identify bugs. My dedication to knowledge sharing is reflected in my mentorship of junior engineers and my involvement in the interview process, where I helped shape new coding challenges.
