Datawarehousing
During my time at Aquon, I played a pivotal role in the design, build, and ongoing maintenance of a robust cloud data warehouse solution.
Technologies Used
Dashboarding
A look at a multitude of dashboards I have built over the years as a Data Engineer at my time at Aquon.
Technologies Used
Anomaly Detection
I developed an automated system designed to detect and correct anomalies in incoming sensor data from the field. This system efficiently identifies outliers, removes them, and then imputes the missing values using a Random Forest Regressor.
Technologies Used
Sensoring Modem
I architected and constructed a sensoring modem designed for autonomous data registration and transmission. The core of this solution lies in its connectivity to the Azure IoT platform.
Technologies Used
Sensoring Platform
I developed a comprehensive sensoring platform designed for robust data monitoring. This end-to-end solution leverages the full Azure data stack.
