i-spark makes data extra valuable for WWL

How hands-on expertise in data architecture, engineering, and analytics helped WWL make smarter, faster decisions.

Client snapshot

WWL Holding is a leading lighting specialist, offering both conventional lamps and future-ready LED solutions. With 24 webshops in 15 countries, the company serves a large customer base across Europe while making a meaningful contribution to sustainability and the greening of the continent.

Why WWL partnered with i-spark?

While WWL has its own internal data department, it partnered with i-spark for practical, hands-on support in: data architecture, data engineering, machine learning, dashboarding and data analytics. Together, we enhanced the team’s knowledge and elevated the strategic value of their data.

What was the challenge?

A rich data ecosystem, locked in silos

WWL relies on a wide variety of systems across its digital operations. Data comes from:

E-commerce platforms
Warehouse management software
Customer support solutions
ERP systems
Marketing automation tools

The volume and value of this data were clear but it lived in separate environments. WWL needed support in unlocking and combining these sources to power business insights, compliance needs, and continuous optimisation of their webshop ecosystem.

What was our solution?

Unified platform, smarter operations

Data engineering infrastructure

i-spark developed a data platform on AWS to centralise and process data efficiently.

- Custom ELT pipelines via AWS Lambda and AWS Glue
- Integration with third-party tool Dataddo
- Raw data collected and stored hourly in AWS S3 (Data Lake)
- Processed data loaded into Amazon Redshift for analysis

Data modelling with dbt

Given the size of the datasets across 24 webshops, we used dbt (data build tool) to transform raw data into scalable, structured models and optimise the performance by reducing the burden on dashboarding tools.

Dashboarding with Looker

The team at WWL now uses Looker to create clear reports to track webshop effectiveness, marketing performance, and operational KPIs.

Reintegrating data via APIs

In addition to Looker reports, the system we developed sends back ‘Customer Cards’ via APIs to the source systems, enriching the source data with information from our client’s customers. In collaboration with WWL Holding, we continuously work to add more value to the vast amount of existing data.

The impact? Making data extra valuable

Thanks to i-spark, the WWL data team has gained advanced capabilities, making their data truly strategic and exceptionally valuable.

"Thanks to i-spark's expertise, our data is no longer a by-product, it’s a growth engine. We now enrich our internal systems, optimise operations, and inform customs authorities with ease.”
