Elizabeth Martinez Mejia

I'm a Senior MarTech & Analytics Architect. I work as an independent B2B consultant for companies that need their tracking architecture and measurement frameworks untangled fast. I bridge the gap between what marketing directors need to see and what developers actually need to code.

With over 10 years of experience across the UK and global markets, I strip away the guesswork and build clean, scalable data pipelines.

What I actually do:

- Measurement Frameworks: Tying your real business goals to precise technical tracking.

- Ecosystem Audits: Deep-dive troubleshooting of your platform stacks to guarantee reliable data for campaign tracking and attribution.

- The Google Marketing Platform (GMP): Architecture, deployment, and integration across the stack.

- Campaign Analytics: Post-Campaign Analysis (PCA), monthly reporting, and custom dashboarding.

- Data Privacy & Compliance: Google Consent Mode v2, GDPR architecture, and cookie banner integrations.

- Tool-Agnostic Tracking: I fix attribution and tracking across any analytics platform.

- Data Layer Design: Complex schema design and rigorous QA.

Data Visualisation & AI: BigQuery, Looker Studio (Google Data Studio), and implementing AI-driven reporting automations.

I work autonomously, I move quickly, and I care about clean data. Let’s get your tracking ecosystem working properly so you can make confident, revenue-driving decisions.
