Ngoc Huan Nguyen

I build the whole path data takes: collect it from sensors, manage it at the edge, publish it to the cloud, and visualize it on dashboards people use.

Stage 1 · Collect

Raw input:
who I am.

Sensors sample the world. Here is the first reading, about me.

I design end-to-end IoT systems: low-power nodes that run for years on a battery, gateways that keep working on flaky networks, and cloud pipelines that turn raw readings into decisions.

I care about what makes devices trustworthy in the field: OTA updates that can't brick, secure provisioning, and monitoring you can actually debug at 3am.

Stage 2 · Manage

Filtered, structured,
ready to ship.

At the edge, data gets cleaned and organised. These are my skills, sorted by layer.
