MARS - Snickers Hungerithm, stock exchange for chocolate bars

The Hungerithm is like a stock exchange for Snickers chocolate bars. Prices of the bars fluctuate in real-time, based on the online mood of the internet.
When anger goes up, Snickers prices goes down at every 7-Eleven stores. Prices are updated 144 times a day, and drop as low as 82% off the normal shelf price.

Technology
Built upon Google Deep Learning models for Natural Language, the Hungerithm is a bespoke service scanning over 14,000 Twitter posts a day. The mood of the internet, affecting the chocolate bars price in real-time, is calculated by extracting sentiment and processing the output into a bespoke algorithm that can normally distribute and deviate results over time. It can understand slang, sarcasm, emoji’s and differences in context.
The interactive client-side interface was built with VueJS and allowed customers to monitor fluctuating prices and redeem coupons in real-time. Engineered around AA accessibility requirements and the ability to switch locales, currencies, and reading direction based on local market needs. A bespoke interface was also created for community managers to moderate all public content appearing on the client-side interface.
The infrastructure was built and deployed on Amazon AWS using infrastructure-as-code. With a centralised GraphQL API and a serverless architecture leveraging services likes Fargate, Aurora, Lambda, S3 and CloudFront. Designed to be easily deployed in different regions and markets.
