About the project:

Client: Metrikus

Location: London, UK

Industry: PropTech, SaaS, IoT

Team Size: 3 Developers + DevOps + PM + BA + QA

Project Duration: Long-term engagement

A UK-based PropTech company approached Interexy to accelerate their platform development and address critical performance bottlenecks. With growing demand from major enterprise clients Metrikus needed to rapidly scale their data processing capabilities while maintaining system reliability.

Project functionality Project idea and features

The client is a British PropTech platform specializing in building efficiency management and smart building technologies. The platform provides a comprehensive solution for transforming building data into actionable insights.

Key features include:

  • Centralized Data Hub: Aggregates and normalizes data from thousands of IoT sensors and existing Building Management Systems (BMS) into a single, unified platform;
  • Customizable Dashboards: Allows users to visualize complex data streams in real-time through intuitive and configurable dashboards;
  • Advanced Analytics & Reporting: Enables the creation of detailed reports, custom alerts, and automated rules to monitor building performance proactively;
  • Unified API Access: Provides a single, powerful API, simplifying access to all building data for custom integrations and third-party applications.

Project delivery Development process

Our role involved comprehensive platform development and optimization to support the company’s growth and scalability needs.

On the backend, we engineered a scalable data ingestion system for diverse IoT sensors and re-architected the data querying logic, which resulted in a 30-40% performance increase in analytical dashboards. On the frontend, we developed a new suite of interactive data visualization components in React, empowering users to intuitively understand real-time building metrics.

We also executed a systematic refactoring of the legacy backend, a foundational effort that improved system stability, reduced technical debt, and increased overall maintainability.
