Improving e-commerce customer experience for global home appliances manufacturer through technology
79% fewer duplicate API calls
18s faster page loads
400k+ lines of code optimized
Brightdome improved ecommerce experience and conversion rate of a global home appliance manufacturer with a dedicated optimization squad removing friction across critical journeys.
A leading home appliance brand relied on a SAP Commerce Cloud ecommerce site that had grown complex and slow. Brightdome reframed a planned audit into a targeted assessment and continuous optimization squad focused on performance, UX, and clean code. Across multiple waves they removed redundant API calls, streamlined checkout, and improved Core Web Vitals, delivering faster shopping journeys and a backlog of prioritized improvements.
THE CHALLENGE
Performance drag on critical ecommerce journeys
The client runs its direct to consumer channel for the North American market on a mature SAP Commerce Cloud implementation. After years of incremental changes, the site had become slow, brittle, and difficult to evolve. Core Web Vitals were failing on home, search, and product pages, and shoppers frequently encountered long load times, visual shifts, and inconsistent behavior across devices.
Behind the scenes, duplicated API calls, heavy scripts, and limited caching created unnecessary network traffic and processing overhead. The codebase spanned hundreds of thousands of lines across multiple front ends and a shared backend, with duplicated components and little visibility into code quality. Governance and delivery practices also showed gaps. There was no automated testing or continuous performance monitoring, deploys relied on manual builds and cherry picked releases, and lost pull requests made it hard to track what was in production.
These issues threatened both revenue and marketing investment for a flagship appliance brand. Leadership needed a partner who could quickly identify the highest impact fixes, stabilize the platform, and lay the groundwork for a structured backlog of performance and experience improvements.
OUR APPROACH
End to end technical discovery and optimization delivery
Brightdome designed a parallel assessment and build plan to start delivering impact in production from the first weeks. A cross functional squad spanning solution architecture, senior engineering, UX, QA, and product leadership ran discovery sessions with client stakeholders to map pain points across performance, architecture, and governance, then agreed to focus this phase on performance while documenting longer term opportunities.
The team executed a structured technical assessment using its Digital Strategy and Software Engineering practices, including heuristics reviews of core journeys, exploratory tests on key devices, heatmap analysis, and a thorough code audit in Brightdome’s Sonar environment across front end and backend services. This produced a prioritized backlog covering duplicated calls, caching gaps, render blocking scripts, unused CSS, and accessibility issues. Brightdome then organized the work into multi wave sprints, anchored by quarterly PI planning and two week iterations.
Early waves concentrated on product listing, product detail, and checkout, where performance issues were most visible to shoppers. Engineers implemented targeted fixes while QA ran regression tests and the team introduced ongoing Core Web Vitals and navigation tracking to feed future backlog grooming and growth oriented initiatives.
RESULTS
Faster, stronger journeys equals improved customer experiences
Across the engagement, Brightdome partnered with the client team to address key performance challenges and turn the ecommerce platform into a faster, more reliable growth engine. The squad removed major performance bottlenecks, cutting duplicate calls by up to 79% across home, product listing, and product detail pages, and delivering page loads more than 18 seconds faster on key journeys.
Brightdome audited 400K+ lines of frontend and backend code in its Sonar environment, resolving critical clean code, duplication, and maintainability issues that improved Core Web Vitals on the templates that drive revenue and stabilized navigation and checkout flows. Shoppers now move smoothly from discovery to purchase, and the brand can confidently scale traffic and campaigns on a cleaner, more observable platform with a clear roadmap for ongoing CX optimization.
