AquaSafe
Real-time water-quality monitoring across a distributed sensor network.

AquaSafe ingests high-frequency telemetry from a network of water-quality sensors and turns it into something a human can monitor in real time. The engineering question was how to get from 50+ noisy streams to a sub-second alert without drowning in data.
The build
- Designed a MySQL schema optimized for time-series queries across 50+ sensor streams, getting alerting down to sub-second.
- Built a full-stack monitoring platform in React and Node.js with interactive dashboards for live and historical sensor data.
- Architected a multi-station sensor network for centralized monitoring and anomaly detection across distributed sensors.
Recognition
Placed 3rd out of 200+ systems at the SEECS Open House 2023 — a useful reminder that the unglamorous schema work is often what makes the demo feel instant.
