Personalisation plugin for an e-commerce platform

Recommendation and search-ranking models packaged as a plugin for the client's storefront.

recommendation latency

Challenge

Generic "bestseller" widgets and keyword search were leaving revenue on the table.

What we built

  • Session-based recommendation models and a learning-to-rank layer for search.
  • A low-latency serving API with feature caching, deployed as a storefront plugin.
  • A/B testing framework to prove impact before full rollout.

Results

Recommended-product revenue rose by around 18% in the A/B test, and the search ranking improvements were rolled out to all traffic.
