Experience

More than eight years in consulting, five of them working with Customer Data Platforms daily. The clients in these roles belonged to my employer, so I describe them by sector.

MarTech Solution Architect

Capgemini Feb 2025–Jul 2026

Client: one of Spain's top insurance companies

  • I won a competitive RFP against Big 4 firms with the technical assessment and the CDP architecture proposal.
  • I built the AJO journey ecosystem, with identity stitching through Query Service and Decisioning on the Web SDK.
  • I took data governance and consent management from design to production. I cut duplicate profiles by around 30%.

MarTech Engineer Associate Manager

JAKALA May 2024–Feb 2025

Client: a major banking institution

  • I coordinated the AJO migration with the technical team, through to the first use case in production.
  • I designed the XDM data models for bulk ingestion, on an AEP architecture of 8 million profiles.
  • I consolidated more than 30 email campaigns from Pega, and planned the Adobe Analytics to CJA migration.

Experience Transformation Consultant

Accenture Song Mar 2021–Feb 2024

Client: a major bank

  • I rebuilt the data layer across web, the logged-in area and the app, coordinating a team of 5.
  • I owned the full measurement layer: Adobe Analytics, the Tealium iQ and EventStream libraries, and data quality.
  • I set up server-side tracking with EventStream and sGTM, plus CMPs from scratch. Campaign ROI rose 15%.
  • I was the Adobe Target reference: implementation audits, environment and workspace governance, and integration troubleshooting.

Technical Digital Consultant

Metriplica Mar 2018–Mar 2021

Client: retail, fashion, travel and automotive accounts

  • I standardized and rolled out the measurement setups for 4 corporate accounts.
  • I migrated a fashion retail account from Universal Analytics to GA4 as soon as the platform shipped.
  • I ran tag management across Adobe DTM, Adobe Launch, GTM and Tealium iQ. Reporting went from days to hours.
  • I implemented the iOS and Android analytics SDKs, and defined the A/B testing flow for a retail client.

Tech Architecture Delivery Analyst

Accenture Technology Oct 2017–Mar 2018
