  Kaltura (https://corp.kaltura.com/): I lead a team of three developers. Developing an application for the Android TV / Apple TV / Mobile platforms using You.I engine (fork of React Native). Also, worked closely with the You.I team in solving complex problems with performance / crashes / memory leaks in You.I. Consumer Fusion (https://www.consumerfusion.com/): Working alone with this project (mobile development), I rewrote applications from scratch on a new stack. During development, a number of interesting (but not very complex) things were implemented in React Native: working with layers (overlaying stickers on an image), working with bitmaps (lossless compression, working with metadata), as well as full application fault tolerance in case of unavailability /change backend API. Wazo (https://wazo.io/): As part of my work, a performance audit of the application was carried out, a refactoring plan was created, and a number of critical problems with the application were solved: crashes, building scripts, offline support and low internet connection mode (сounting and analysis). The main focus of my work: help in solving complex internal problems with the application. I am a Typescript and React Native mentor: actively helping in interviewing candidates for the company.
