Client

A global provider of ESG ratings, offering insights into companies’ environmental practices, social responsibility, and employee well-being.

Need

The client sought our professional ecommerce development services since they needed a scalable ESG rating platform with subscription-based access together with a premium website for a superior user experience. The existing platform was experiencing slowdowns in performance and stability and required an optimization approach that would maximize performance, security, and release reliability.

Solution

Working closely with the client’s team, our specialists optimized the platform to deliver a seamless and user-friendly experience while ensuring scalability and efficiency. Now, subscribers don’t have to dig through mountains of reports but get only the most relevant ratings and analysis based on their unique preferences.

To enrich the experience for high-value customers, we also built a premium site with Node.js, prioritizing usability and performance. This wasn’t just a UI refresh, but a structural upgrade that enabled faster access to insights, intuitive navigation, and a frictionless experience.

As the platform scaled, we had to deal with performance, security, and deployment challenges and specifics. Addressing these required targeted optimizations across several areas.

Optimization areas

Optimizing performance & code quality

As the platform scaled, inefficiencies in the codebase and database began slowing things down. Using profiling tools and diving deep into SonarQube reports revealed areas for optimization, resulting in extensive refactoring and query optimization.

The largest fix was a database query that lasted a full four minutes. By optimizing indexing and re-writing the queries, execution time fell to milliseconds, a big win for responsiveness and user experience.

Security

With more businesses relying on the platform, security became a top priority. We integrated Git-based security scans into the CI/CD pipeline to proactively detect and block vulnerabilities before they become an issue.

Deployment & multi-environment configuration

A scaling platform requires a sound deployment strategy, so our team built a structured deployment pipeline across Development, QA, and Production, allowing for seamless updates with minimal downtime.

To further ensure stability, we implemented rigorous unit and integration testing, targeting 90% test coverage. This ensured every release was solid, reliable, and production-ready. The result was a bi-weekly release cycle that keeps improvements rolling out without breaking existing functionality.

Outcomes

Efficient subscription-based platform

Users receive tailored ESG ratings and insights, improving engagement and content relevance.

Optimized database performance

Search queries now execute in milliseconds, significantly improving responsiveness.

Premium experience with a dedicated website

The Node.js-based premium platform enhances user interaction and service accessibility.
