Why Cognito

I chose the name Cognito from the Latin cognoscere – "to learn, to come to know" – because it describes how I work. Before I propose architectures or models, I spend time understanding how your business really operates. From there, we design software and AI solutions that fit the way you work, not the other way around.

Medical Device Event Analysis

Used large language models to read and sort narrative medical device event reports, making safety summaries clearer and helping teams spot potential issues earlier.

Recycling Supply Chain Forecasting

Built time-series forecasts for inbound recycled materials so planning, inventory decisions, and collaboration across the recycling value chain could rely on more predictable flows.

IoT Sensor Data Pipeline

Set up a data pipeline that continuously processes sensor data from industrial equipment, using cloud services and storage that keep the data ready for analysis and follow-up.

Energy Storage Alerting

Designed a system for real-time monitoring of residential energy storage, surfacing clear alerts when patterns suggest that something may need attention.
