A decade of building and maintaining digital platforms for Tesco

CODEWAVE built and operated Tesco’s custom CMS, CRM solutions, web applications and on-premise infrastructure, supporting the business as its digital needs evolved.

About the client

Tesco is one of the world’s largest grocery and e-commerce retailers, operating thousands of stores and serving millions of customers across physical and digital channels. With more than 340,000 employees across the Group and a large-scale online grocery business, Tesco operates in an environment where digital platforms need to remain reliable, responsive and ready to support high volumes of customer activity.

Key insights

Visual CMS wizard

Editors build and enhance site modules and services without code.

Seamless integrations

Stable links to external data sources, CRM, and internal tools.

Performance & uptime

Measurable speed gains and reliable infrastructure operations.

Trusted partnership

A decade-long collaboration since 2003, with continuous delivery and support.

The challenge

Tesco needed a flexible, high-performing solution to manage content and service modules across its large-scale web ecosystem. The platform had to stay fast, consistent across markets, and easy to maintain - even as new features were introduced over time.

Flexible content management

Editors needed a way to create and update modules without relying on developers.

Consistency across markets

Ensuring uniform experience across pages, languages, and regional sites.

Seamless integrations

Connecting smoothly with existing CRM systems and external data sources.

Reliable infrastructure

Maintaining speed, uptime, and stability at scale.

Controlled development scope

Delivering continuous improvements within a fixed, efficient framework.

The solution

CODEWAVE partnered with CzArt Advertising Agency to take responsibility for the technical delivery, development and ongoing maintenance of Tesco’s digital platforms. We built a custom CMS around Tesco’s editorial workflows, including a visual content builder that allowed editors to create, manage and update website modules independently. This reduced the need for developer support in everyday content management and gave Tesco’s team greater control over Tesco.pl. Key solution elements:

Custom CMS architecture

Engineered for high performance and aligned with Tesco’s content workflows to ensure flexibility and reliability at scale.

Visual content wizard

Enabled editors to build and reuse content blocks, service components, and promotions with consistent styling and behavior.

Integration layer

Seamlessly connected the CMS with CRM systems and external data sources such as product and promotion feeds.

Role-based workflows

Introduced access controls and publishing permissions to streamline collaboration and maintain editorial quality.

Infrastructure optimization

Continuously monitored and fine-tuned for speed, uptime, and long-term stability under heavy traffic.

Documentation and onboarding

Delivered clear documentation and training to help teams stay efficient and self-sufficient as the platform evolved.

"Thanks to the dedication and experience of CODEWAVE team our cooperation has been successful for over 10 years. Solutions they provide are critical to the functioning of Tesco's website. I would recommend CODEWAVE to anyone looking for comprehensive software development service for their web applications."
