Stop your customer data investment from stalling.

Adobe Experience Platform at the core, plus Tealium Data Hub, measurement, tracking, and consent. Barcelona and remote.

Open to contract roles and consulting engagements. I also consider selected permanent roles with a strong technical scope.

Does this sound familiar?

Problems that look like platform issues and are usually architecture, data or operating issues.

  • 01

    AEP is live, but identity does not resolve and every use case uncovers another exception.

  • 02

    Web, apps, analytics, and activation collect different data, or consent does not reach the destination.

  • 03

    You are comparing a suite with composable or warehouse-native options and need to decide before signing.

What I fix

MarTech implementations stall when the data model, collection, identity, and consent evolve separately.

I work from architecture through configuration: CDPs and journeys, web and app measurement, Tealium, server-side delivery, and governance. Then I document the result so your team can operate it.

Identity and consent travel with the data from collection onward, in real time and in batch. Adding them later is what stalls implementations.

Customer data flow diagram. On the left, collection, with two cadences: web and app and server events as streaming, CRM and core systems and historical loads as batch. In the center, the identity contract and consent, which all data from the four sources passes through. Then the unified profile with its audiences and its state, and below it Decisioning, which resolves the next best action. On the right, activation: journey analytics reads from the profile; journeys and campaigns and destinations and media come out of Decisioning.

Where I can come in

Four highlighted engagements from a broader offer. Each has a defined start, deliverable, boundaries, and next step.

  1. 01

    Architecture and implementation audit

    I assess an existing MarTech implementation and turn the observed problems into prioritized findings and a remediation plan.

  2. 02

    First production use case

    I build one complete use case, from the agreed source through to an activation or journey that the team can operate.

  3. 03

    Measurement and tracking architecture

    I design or rebuild data collection across web and apps so events, identities, and documentation follow the same contract.

  4. 04

    Platform selection

    I compare requirements with real capabilities and expose the integration, operating, and ownership trade-offs before recommending an option.

Projects

Two data and architecture projects presented anonymously to preserve confidentiality.

01 / one of Spain's top insurance companies

Greenfield Real-Time CDP implementation in insurance

The organization did not have a CDP. The project had to introduce AEP as a shared data, orchestration, and personalization layer, and deliver a working MVP first. The architecture had to support historical loads, real-time events, and later evolution without rebuilding the foundation.

02 / a major bank

Measurement, consent, and CJA architecture at a major bank

Measurement was split across the public site, the logged-in area and the app, each with its own implementation. Without a common data layer, neither reporting nor activation could be trusted.

Architecture patterns from production

Seven visual notes on the decisions that fail after launch: identity contracts, shared profile state, channel reuse, Decisioning and operational handover.

  1. 01 / Identity Identity is a source contract
  2. 02 / Customer state Separate operational state from customer state
  3. 03 / Profile governance Profile writes are shared-state engineering

Check it yourself before writing to me

Four short technical reviews that order what to look at first. They run in your browser, send no answers, and ask for no email.

  1. 01 CDP architecture Data model, identity, profile, consent, activation, and operations.
  2. 02 Measurement and tracking Questions, event contracts, identity, releases, quality, and destinations.
  3. 03 Technical consent implementation Inventory, propagation, collection, minimization, destinations, and operating evidence.
  4. 04 Vendor evaluation briefing Vendor claims, verification questions, evidence, and ownership.
