I have acquired broad experience with developing backend, business logic and infrastructure around cross-platform Dart/Flutter mobile apps. As part of that, I have also done research work while developing complex algorithms and models (device movement and position tracking, recommendation model), that were essential for our products.• Developed a model to compute device flight information by analyzing sensor data.• Developed an algorithm for removing centripetal acceleration noise from accelerometer data. • Developed a recommendation model based on tags and other users’ data.• Extensively integrated Firebase services into mobile applications.• Designed a NoSQL data model and integrated it into the application.• Contributed to popular open-source dart/flutter packages (sensor_plus).

The goal of the role was to optimize the project. In particular, the testing time of the project could last from one hour (if you were lucky) to several hours, which resulted in costly developer idle time, complicated and generally unstable behavior of the project.• Fixed dozens of flaky tests or the underlying serious bugs in asynchronous source code.• Reduced testing time by 30%, which significantly reduced deployment time and server costs. • Developed a Jenkins extension to detect flaky test in CI.• Added test health metrics.
