Company Background

Our client is a well-known eyewear brand with a strong online and retail presence, recognized for making affordable, stylish glasses. Their backend engineering teams support a robust product catalog and promotional engine, powering consistent and efficient data flows across digital platforms.

Project Description

The project is focused on building and supporting two core backend systems: a Catalog service that transforms and denormalizes upstream product data using PostgreSQL, then projects it into ElasticSearch and DynamoDB for downstream use; and a newly developed Promo Engine written in Go, which manages promotions and promo codes. The initial task includes migrating promotional logic from a legacy backend to the new microservice. The architecture follows Event Sourcing and CQRS patterns, deployed using a HOT/HOT model in AWS and managed via Terraform. Additionally, the system includes bi-directional synchronization with third-party EHR platforms, ensuring real-time data consistency across systems.
