Data platform modernisation

Data platform modernisation that makes data engineering self-serve

Two members of the Equal Experts network mapping a process at a whiteboard with post-it notes

We deliver data platform modernisation on Snowflake and Google Cloud Platform — not as a one-off migration, but as a shift in how your organisation builds, owns and operates data pipelines going forward. Our Snowflake consulting experience spans enterprise-scale engagements, alongside the tooling — dbt, Collibra, Tableau — that turns a data warehouse into a usable analytics platform.

Where we've delivered

Built with John Lewis Partnership

Snowflake had already been selected as JLP’s Partnership Data Platform in 2020, but individual teams were still building pipelines from first principles every time. We formed a blended team — Partnership and Equal Experts data engineers, product owners and data management experts — to build the Paved Road: a repeatable, re-runnable process built around a data product definition. As of August 2024, there are 90 data products live on the Paved Road, enabling teams to launch over 150 data pipelines without depending on a central data engineering team.

Modernisation means self-serve, not just migration

A lot of GCP data platform and Snowflake engagements stop at the migration. We go further: domain teams build and own their own data products instead of queuing behind a central team, and the platform is treated as an ongoing product with its own roadmap — not a project that ends at go-live.

Technology we work with

Snowflake for warehousing and self-serve data pipelines, including performance and cost optimisation at scale. GCP, including BigQuery migration paths for organisations consolidating from multiple prior attempts. dbt for pipelines as code. Collibra for governance and cataloguing, so data products stay discoverable as the platform scales. Tableau for analytics on top of the modernised platform.

FAQ

What is data platform modernisation?

Moving data infrastructure onto modern cloud platforms like Snowflake or GCP, and changing how pipelines are built — from centralised, bespoke work to a repeatable, self-serve data pipelines model.

Why Snowflake over a traditional data warehouse?

Snowflake separates storage and compute, so each scales independently without contention. With dbt and Collibra alongside it, that supports a genuinely self-serve model rather than one team owning every pipeline.

How long does modernisation take?

We typically start with a focused review, then build a reusable capability with a blended team — value compounds as more teams and data products come online.

What’s a “data product“?

A pipeline and its outputs treated as an owned, documented, reusable asset — with clear ownership and a defined interface — rather than a one-off script.

Do you work with GCP as well as Snowflake?

Yes — we’ve delivered Snowflake running on GCP data platform infrastructure, and broader GCP-native data engineering.
