Basic functionality is same as at Amazon Mechanical Turk, but in addition to that there's tasks routing capabilities between different stages with custom acceptance, rejection criterias, which allows building complex workflows. System is supposed to serve as abstract task processing engine for other client subsystems. Besides that, TaskProcessor was a pilot project utilizing client's new application platform based on approach of micro-services (Dropwizard with certain customizations) interacting with each other through command abstraction layer (Hystrix framework). Due to this, besides business related development there were activities related to adoption and improvement of new platform. Participation: API and server-side infrastructure design and development.

It includes iOS and Android client apps and also server application. Most of the system features are location based, which requires additional server-side processing of client location information and handling numerous "something near something" queries. Also, system functionality does heavy use of push notifications to deliver various updates to clients(Apple APNS at the time of working on the project) Participation: Server-side infrastructure design and implementation. Participation in designing overall system architecture. Implementing geo-location services, push notifications service connector.
