Implemented saving ujet entities as Salesforce/Zendesk custom objects, made improvements to CRM module error handling and validation. As part of work on validation module, I proposed and implemented js function argument analysis tool, which helped to discover several bugs and unused variables.

My contributions were development of a game items shop and game tutorial for the new players. During shop development I proposed and implemented isomorphic client-server app feature with client-side actions queuing and simulation.

The main issue was ranking algorithm development, which was based on real-time statistics aggregation (number of page likes, visits, etc). I have made a prototype for calculation of aggregates with map-reduce algorithm over time-sliced event streams.

This was a single person full-stack development. Initial prototype was developed with rxjs/Framework7 on the frontend and rxjs/ Node.js on the backend. The main issue was support of push notifications and in-app messaging with history sync.

This role included research for backend and game engine improvements. As part of the research I provided Node.js-based backend prototype implementation.
