Custom Facility Monitoring SaaS Platform

Overview

Architected and built a production SaaS platform for building and HVAC analytics, supporting real-time ingestion, visualization, and mobile access.

Problem

Customers needed a centralized platform to visualize and analyze HVAC and building system data collected from deployed IoT devices, accessible both on the web and mobile.

Constraints

• • Real-time data ingestion from thousands of devices
• • Long-lived historical data storage
• • Shared backend between web and mobile
• • Small engineering team
• • High uptime and reliability expectations

Solution

I co-designed and developed a customer-facing analytics platform. It features backend ingestion pipelines receiving device data, PostgreSQL-based storage for time-series (TimescaleDB) and metadata, a Web dashboard built with Next.js and TypeScript, and a Mobile app built with Expo / React Native, all sharing a backend architecture.

Architecture (High Level)

IoT Devices → AWS Ingestion → PostgreSQL - TimescaleDB → Web Dashboard (Next.js) → Mobile App (React Native)

My Responsibilities

• • Backend architecture and infrastructure
• • Database design and ingestion pipelines
• • Frontend platform architecture (with frontend engineer)
• • Mobile app architecture and integration
• • Application deployment and operations

Impact

• • Enabled customers to monitor building performance in real time
• • Provided a unified platform for HVAC diagnostics and analytics
• • Supported enterprise-scale customer deployments
