TL;DR Stackshare

Our app consists of four main parts:

• Backend; Here we use microservice based approach with services build using Golang and Python.
• DevOps; We use AWS EC2 as our infrastructure provider. All our microservices are running using supervisor to provide demonization and easy restart/logging access. We use AWS Route53 for DNS related things. Every app is running behind nginx reverse proxy.
• AI; We use two frameworks. CatBoost for Python implementing gradient boosting on decision trees with a native support of categorical features and GoML for Golang to perform sentiment analysis via Naive Bayes classification.
• Frontend; We have build responsive landing page using ES6/Bootstrap/jQuery
