Goal: Creation of a real-time betting odds comparison engine/database. The platform will receive real time odds data from a number of different sources (XML feeds, API updates, Push/Pull subscription, scraping, etc.) from a number of different betting providers. Messages are buffered in AMQP queues and inserted into data source specific data marts. We intend to create a single unified view of all data sources using a new matching system, that has to: - Process about 100-500k records per minute. - Be resilient to failures of individual data sources, replacing them with fallback options as required. - Be highly configurable, but will utilize automated matching methods where possible. The aim of the platform is to provide near real time information of combinations that allow our users to identify the most profitable betting strategies such as: - Matching bookmaker and exchange odds. - Identification of profitable accumulator combinations. - Three way matching of outcomes with bookmakers. We will push all data updates to bespoke data marts for these applications, that support: - Reactive data updates - Searches and the definition of filters on the data. - Events and Alerting The aim of the software is to provide a tool that finds close matches between “Back Odds” provided by the bookmakers, and “Lay Odds” provided by the betting exchanges. The matching process will need to find all relevant data for specific events or betting outcomes (for example, matching up all back odds for “Manchester City” to win a specific football match against relevant lay odds for the exact same outcome). The matching logic will be written in Python. It will need to support variations in team names (e.g Man City, Manchester City, Manchester City FC) by way of some central database of acceptable team name variations. Data is ultimately output into a final table that compares bookmaker back odds against exchange lay odds for the same event. http://puu.sh/qxupQ/1a3eba4969.png Essential Skills; - Experience in data processing and analysis.
