Ilia Vorobev
Ilia has been developing on Android for more than 12 years. For the last 4 years he has been helping large companies improve the performance of their mobile apps. The main lesson learnt from the last four years of his career: performance issues are like radiation — they may not be visible to a developer without instrumentation, but they are no less damaging to metrics vital to the business.
