Technical lead and API/Front-end developer

Ladder is a fun dating game. My role was as the Technical Lead and to build the API for the mobile app. I used Ruby on Rails for the API and a Web interface for the admins. The API provides the following features:

  • Users: Creation/edition/deletion – Get profile – Add/Remove/Get photos – Check if a username is available – Authentication/New password request
  • Matchmaking: Get list of matches – Creation
  • Contacts: Creation/Edition – Get list
  • Search a location
  • Pricing: Get pricing – Get user transactions – Transaction creation
  • Games: Creation – Get list – Start new round – Etc.
  • Messages: Creation/Edition – Get list
  • Custom Questions: Creation – Get list – Report

The API was developed with the JSONAPI::Resources framework.

Then I built a Facebook bot that replicates the game mechanism and that allows to play with Facebook friends.
