Motivated to build hardware to last for ages.
I am experienced and specialized in embedded devices, IoT devices, product engineering design, robotics, and AI engineering, which comes from being an assistant lecturer and research assistant.

Forked from ANTRAC 1.0 to replace uniform broadcast spraying with calibrated canopy dosing: a commanded volume becomes a pump runtime at 12.6 mL/s across three tank paths, bounded by a 180 mL floor and a 560 mL cap.

Four-wheel unmanned ground vehicle built to scout chilli rows and detect anthracnose under field light. It carries its own power over uneven soil and isolates the sensor head from chassis vibration. Detection is this project; the dose-controlled station is its fork.

Two-axis tracking station for charging field machinery off-grid. The build models and drives the tracker so the panel follows the sun along both azimuth and elevation instead of sitting at a fixed angle. Energy gain over a fixed panel is not claimed here: it was not measured.
