How I can help
Whether you need a data foundation built from scratch, a second opinion on the one you have, or someone to lead the whole function for a while, I can help!
I work with teams worldwide, remotely or on-site if you’re in Berlin.
Data Strategy & Data Audit
Before anything gets built, it’s worth knowing what you actually have. I audit your current setup, map it against where the business is going, and give you an architecture and roadmap you can act on, not a slide deck that ages in a folder.
Data audit: what exists, what’s broken, what’s missing
Target architecture designed around your business model, not a vendor’s
Prioritised roadmap with realistic sequencing and cost
Tool and platform selection (GCP, AWS, and the modern data stack around them)
Often the first engagement: several clients have started here and then hired me to implement it.
Data Warehouse & Pipelines: Your Central Source of Truth
Most reporting problems are really data problems: three tools, three numbers, nobody sure which one is right. I build the central source of truth that ends that argument, a warehouse or lakehouse where every number has one definition and one home.
Data warehouse and lakehouse builds in BigQuery, Redshift, and Postgres
Pipelines and API integrations across Shopify, WooCommerce, Amazon Seller Central, GA4, Salesforce, Meta Ads, Firebase, apaleo, and more
Dimensional modelling and the business logic that turns raw data into something usable
Customer data unification and deduplication, including ML-based identity matching across records
Built for e-commerce, subscription, SaaS, and hospitality clients, from a lean three-month mini-warehouse to a multi-year lakehouse.
Dashboards, KPIs & BI Reporting
A dashboard nobody opens is a cost, not an asset. I start from the decisions your team needs to make, define the metrics that drive them, and build reporting people actually use.
KPI definition and metric hierarchies tied to how the business grows
Dashboards in Looker Studio, Power BI, and Sisense
Domain reporting: revenue, marketing performance, P&L, product, customer and guest insights
E-commerce and subscription metrics done properly: LTV, AOV, retention, cohorts, product stickiness
Internal and external/investor reporting
Reporting suites delivered for serviced-apartment operators, D2C brands, and subscription apps.
AI, Automation & Data Products
Once the foundation is solid, data stops being a reporting exercise and starts being leverage. I build the products and models that turn your warehouse into something the business compounds on.
Machine learning models: recommendation engines, personalisation, identity resolution
“Talk to your data”: connecting your warehouse to LLM assistants for conversational analytics
Automation of manual reporting and operational processes
Event tracking and experimentation frameworks, including server-side tracking and A/B testing
Proofs of concept that come with a real scaling recommendation
From deep matrix factorization recommenders serving 4,500+ pieces of content, to LLM-connected warehouses shipped this year.
Fractional & Interim Data Leadership
Some companies don’t need a project. They need someone to own the data function until it can stand on its own. I step in as your fractional or interim head of data, set the direction, and build the team that replaces me.
Ownership of data strategy and roadmap alongside your growth and product vision
Team building: hiring, structuring, and leading data analysts, scientists, and engineers
Working directly with founders and C-level to make data part of daily decision-making
Vendor, budget, and stakeholder management
Handover: documentation and knowledge transfer so your team keeps the momentum
I’ve held this role at both ends: as an in-house head of data building a team of seven, and as a fractional head of data owning the domain remotely.
Data Literacy Coaching & Team Enablement
The best warehouse in the world fails if nobody trusts it or knows how to ask it a question. I coach teams and leaders to read, question, and act on their own data.
Company-wide dashboard and BI training
One-to-one coaching for founders and executives on building a data culture
Workshops on metrics, experimentation, and evidence-based decision-making
Guidance on hiring for data roles and structuring the team
Delivered as a standalone engagement or built into a larger project so the handover actually sticks.
