Personalization at scale was a pipedream. The best anyone could do was slice users into broad audiences — and even that meant creatives and developers hand-building every campaign from scratch. Nexus turns it into an automated system where marketers define the goals and variants. The machine learning engine (Thompson Sampling) autonomously decides what, when, and how to message each of 50M+ users, learning continuously from real engagement. I built the pipeline end to end: user profiles and behavioral signals flow from a BigQuery warehouse through the Hightouch CDP into Nexus, which selects each message and sends it through Braze — and Braze's engagement events flow back in to keep the bandits learning.

A self-service platform that took campaign creation off engineering's critical path: marketers design, localize, and launch cross-channel campaigns reaching 100M+ users. I designed the 24-component creative schema that renders consistently across email, push, in-app from a single source of truth, and the Draft → Approved → Sent governance layer that lets marketers ship safely while the org keeps control of what actually goes out. Impact: 24 campaigns/month now launch with zero engineering involvement, cutting typical launch time from 3 days to 3 hours.
