Data & AI Manager · Senior BI Consultant

I turn messy enterprise data into reporting and AI that people actually use.

I’m Simon. For more than 10 years I’ve built BI, analytics and AI solutions for companies like Accenture, RTL, LEGO and Vaillant. I’m now looking for a permanent Manager or Senior Consultant role, in the Rhineland/Ruhr region or remote.

What I bring

Business sense and technical depth in one person.

Economics background, Scrum certified, and hands-on in the tools. I can talk to the CFO in the morning and fix the data model in the afternoon.

BI, data & AI architecture

Dashboards, data models and cloud data platforms for sales, supply chain, manufacturing and media. Mostly on GCP and AWS, some Azure, plus machine learning and GenAI use cases. Currently Salesforce CRM Analytics+ at Vaillant.

Product ownership for data

PSM I and PSPO certified. I translate what the business needs into a backlog the team can deliver, and I keep stakeholders honest about priorities.

Leading teams

Led teams of up to 10 people at RTL, plus teams at Haavest, LEGO and National Grid. Work planning, onboarding, feedback and a say in hiring.

Selected projects

A few things I’ve built.

RTL Deutschland · Senior Product Manager2021 – 2023

The data mesh platform behind RTL+

For 22 months I owned the media group’s data mesh platform on Google Cloud: product vision, roadmap, backlog and releases. I led a team of 8 to 10, introduced data-as-a-product and federated governance across the business units, and took the platform behind RTL+ from alpha to go-live.

CRM Analytics+ roadmap for Sales, Marketing and Service

I drive the Salesforce CRM Analytics+ roadmap at Vaillant Group, so Sales, Marketing and Service decide on the same numbers. I also build the data transformation and aggregation behind the installer and partner network analysis.

Shop-floor dashboards in manufacturing

Dashboards for the production floor in Weeze, built on data from ERP, production systems and external sources. I did the data modelling and tuning for what the users needed, and wrote the documentation and reporting guidelines so the tools stay easy to use.

Demand planning and supply chain tools

Scrum Master for a team of 6. I kept sprints running smoothly and made sure bugs reported by users were handled fast, so the demand planning tools stayed up while we kept building new applications and data foundations. Stack: Azure DevOps, Tableau, SAP HANA, MySQL and AWS.

BI reporting for the UK gas network

Set up the reporting on telemetry and other complex network data for critical national infrastructure. Strict disaster-recovery protocols and high-availability server deployments were part of the job.
