E-Commerce Recommendation Engine
The Scenario

The problem
being solved

An e-commerce store with 5,000+ SKUs shows the same "bestsellers" to every visitor. Static merchandising ignores browsing signals: categories viewed, time on product pages, cart adds/removes, price sensitivity, brand preferences. Conversion sits at 2-3%.

Algolia Recommendations operates with sub-10ms response times. Nosto delivers individualized experiences. Dynamic Yield offers ML-powered strategies with A/B testing. These prove personalization lifts conversion and AOV.

Mid-market merchants face meaningful monthly costs and integration complexity. Many default to Shopify's built-in "you may also like" using simple co-purchase data.

The Solution

How this
agent works

The agent builds real-time behavioral profiles from clickstream data: pages viewed, products examined, time spent, cart activity, price sensitivity, and category affinity. For returning customers, purchase history and reviews layer on top.

Hybrid recommendations: collaborative filtering (similar customers bought these), content-based (similar along style, price, brand dimensions), and contextual signals (time, device, referral). Different weights for different placements: discovery on homepage, complementary on PDP, completion at checkout.

Recommendations update within the session. A visitor shifting from running shoes to hiking boots sees recommendations adapt immediately. Email uses the most recent profile, not stale purchase data.

How It's Built

A senior engineer integrates directly with your storefront (Shopify, WooCommerce, or custom) via a lightweight JS snippet that streams clickstream events into a FastAPI service backed by Redis for session-level profile state and PostgreSQL for long-term interaction history. Recommendations run through a hybrid model combining collaborative filtering and content-based similarity, with placement-specific feature weights trained in TensorFlow on your historical order and browse data. Initial model training and storefront integration takes 2–3 weeks, with A/B test infrastructure included from day one.

Capabilities
  1. 01

    Session-Level Behavioral Profiles

    The JS snippet streams click, add-to-cart, and dwell events in real time. Redis holds a live per-visitor profile that shifts recommendation weights as behavior evolves within the same session — no login required.

  2. 02

    Hybrid Ranking Models

    Collaborative filtering identifies what similar buyers purchased next. Content-based similarity fills cold-start gaps for new SKUs using catalog attributes. Each placement — homepage, PDP, checkout — uses separately tuned feature weights rather than one global model.

  3. 03

    Context-Aware Placement Strategy

    Homepage widgets optimize for discovery (broad affinity signals). PDP widgets optimize for complementary and substitute items. Checkout widgets target bundle completion. Email triggers use purchase-gap and win-back signals from the PostgreSQL interaction log.

  4. 04

    Built-In A/B Testing

    Experiment infrastructure is part of the base build, not a bolt-on. Compare recommendation strategies head-to-head with statistical significance tracking across conversion rate, AOV, and revenue per visitor — no third-party tool required.

The routine builder was the feature we couldn't get from Shopify. It became the primary driver of repeat visits — customers come back to update their routine as they try new products, not just to browse.
