Develop Your Unified Customer Portal

The Story

The client needed to replace manual, phone-based ordering and fragmented tools with a unified Customer Portal capable of supporting high-volume service operations. They partnered with FiftyFive Technologies as their full-cycle engineering provider for architecture, development, DevOps, automation, and performance validation. A dedicated cross-functional team delivered the portal using a microservices-driven approach to ensure reliability, scalability, and localization accuracy across multiple regions. The engagement focused on building a production-grade platform while establishing an automation framework to accelerate global rollout.

The client is a Sweden-based B2B heat pump manufacturer serving multiple European markets, requiring a scalable digital platform to centralize spare parts, documentation, troubleshooting workflows, and multi-country partner operations.

Challenges

• > Manual ordering flows dependent on phone coordination.

• > No centralized repository for spare parts, documentation, or software files.

• > Fragmented legacy tools requiring separate installations and manual updates.

• > Lack of automated error reporting and operational monitoring.

• > Multi-country workflow inconsistencies and localization differences.

• > Microservices interactions varying across regional configurations.

• > High-traffic performance risks during expansion to new markets.

The Solution

• > Built microservices-based Customer Portal with React.js frontend.

• > Developed GraphQL APIs integrated with PostgreSQL for structured product data.

• > Deployed Kubernetes clusters using Azure DevOps CI/CD for scalable releases.

• > Implemented cron-based error reporting with Microsoft Teams webhook alerts.

• > Integrated Microsoft Clarity for partner usage analytics and behavior tracking.

• > Created Cypress automation suites achieving 90% test coverage across countries.

• > Applied parameterized, region-specific test execution for language/routing validation.

• > Performed load and stress testing using Artillery for high-traffic readiness.

• > Optimized QA pipelines enabling continuous deployment across environments.

The Outcome

The platform achieved 60% partner onboarding in the first year, exceeding the 40% target. Automated workflows reduced manual support load, improved spare parts discovery, and eliminated dependency on phone-based coordination. QA automation reduced manual testing effort by over 60%, enabling faster, safer releases during multi-country expansion. Performance validation ensured the portal could handle traffic spikes across new markets, giving the client a scalable, reliable foundation for long-term growth and stronger partner adoption.
