Strategic Migration & Analytics Governance: Abercrombie & Fitch
The Challenge
As the Web Analytics Tech Lead, I was tasked with modernizing the tracking infrastructure for a global retail giant. The existing setup (Segment) was becoming cost-prohibitive due to data overages, and the decentralized nature of their code repositories led to fragmented data and slow deployment cycles for new marketing initiatives.
The Tech Stack
Tag Management & CDP
Tealium iQ, Tealium EventStream
Analytics & Optimization
Adobe Analytics, Adobe Target
Engineering
React, TypeScript, Node.js, AEM (Adobe Experience Manager)
AI & Automation
Agentic AI Workflows (LLM-based code generation/QA)
The Solution
Accelerated Migration
Orchestrated the transition from Segment to Tealium. By prioritizing high-value event streams and mapping a clean transition logic, we cut the project timeline by 2 months.
Unified Tracking Architecture
Developed a standardized, "write-once-deploy-anywhere" tracking framework across multiple repositories. This involved creating custom TypeScript interfaces to ensure strict data-layer compliance across different product teams.
Automated Governance
To solve the "broken tag" problem, I engineered a schema validation layer. This framework acts as a pipeline blocker; if a developer pushes code that violates the tracking schema, the build fails, and a real-time alert is triggered.
AI-Enhanced Productivity
Integrated Agentic AI workflows into the development lifecycle to automate boilerplate tracking code and documentation, significantly reducing the "time-to-tag."
The "Aha!" Moment
While auditing the checkout flow during the migration, we utilized Adobe Target and Tealium to identify a friction point in the mobile payment selector. By deploying a series of high-impact A/B tests, we validated that a simplified UI outperformed the legacy version, providing a clear data-backed mandate for the permanent UI change.
