Experience
Amax Kids Academy
https://amaxkids.comWhile developing this application, I acted as the project manager and full-stack Unity developer. Two artists and a content creator for children were on the team with me. In this application, I developed a modular engine to run games and activities such as coloring books, educational flashcards, animated books, and puzzles.
We also added an activity database for quick search and automatic creation of UI, a remote content storage system based on Unity Addressables, a localization system for text and assets, and mechanisms and tools required for automatic import of data with texture transformation, generation of scriptable objects, metaparameters, icons, creation, and configuration of asset packs. I developed shaders; more than thirty of them are written by hand, and some are developed in Shader Graph. I was involved in creating 2D skeletal animations.
I also contributed to the development and deployment of server infrastructure.
