RetentionX
Backend engineering on an AI-driven e-commerce intelligence platform — building the data pipeline that turns raw Shopify transactions into customer retention insights.
RetentionX is an AI-driven customer intelligence platform for e-commerce businesses, offering 100+ built-in analyses including RFM analysis, cohort analysis, customer lifetime value prediction, and churn prediction — primarily for Shopify merchants.
I worked as a backend engineer building and maintaining the data pipeline and reporting infrastructure. Raw transactional data was ingested from the Shopify API and stored in MongoDB, then fed into AWS SageMaker to run statistical prediction models. Computed results were persisted in SQL and served to the frontend as structured reports.
The bulk of the work was in the calculation layer — translating raw e-commerce events into accurate, meaningful metrics across varying store configurations. I also integrated Recharge for subscription data alongside the core Shopify pipeline.
