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 Vue.js 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 as code for Amazon AWS. With a centralised GraphQL API and a serverless architecture leveraging services likes Fargate, Aurora, Lambda, S3 and CloudFront. Designed to be easily deployed for different regions and markets.
