01 / SELECTED WORK

Built with purpose.

From circuits to software, a selection of projects exploring how technology can make a difference.

GEOHAZARDS / DECISION SUPPORT01 / 08

GAKIT (opens in a new tab)

Geohazard assessment and flood simulation with satellite rainfall, heat and drought overlays, community reporting, automated validation with staff review as a fallback, and monitoring dashboards.

HARDWARE / MACHINE LEARNING02 / 08

Portable Spectrophotometer

A low-cost, portable spectrophotometer and machine learning platform for estimating analyte concentrations in water. Awarded Best Thesis and Academe Expo champion.

HARDWARE / EMBEDDED SYSTEMS03 / 08

Low-Cost 3D Scanner

A low-cost 3D scanner with bare-metal AVR firmware, infrared sensing, stepper control, and SD card storage for captured point clouds.

MACHINE LEARNING / POINT CLOUDS04 / 08

3D Shape Classifier

A PointNet model that classifies scanned point clouds into 3D shapes, with tools for training, evaluation, and interactive inference.

GEOSPATIAL / ENVIRONMENT05 / 08

GeoSafe

A landslide risk mapping prototype using satellite-derived vegetation change, slope, and soil moisture data.

DIGITAL DESIGN / FPGA06 / 08

32-bit RISC Microprocessor

A processor built in Verilog on a DE1-SoC board, including registers, ALU, memory, and control unit.

EDGE AI / EMBEDDED07 / 08

Drowsiness Detection

A lightweight CNN and embedded detection algorithm designed to run on the low-power MAX78000 microcontroller.

ROBOTICS / EMBEDDED SYSTEMS08 / 08

Wall-Following Robot

Bare-metal AVR firmware combining ultrasonic sensing, PD steering, and obstacle recovery to follow a wall.

A bit about me.

I’m based in Iligan City, Philippines, and studied Computer Engineering at MSU-IIT.

My work includes scientific instruments, geospatial applications, and on-device AI. I also take on freelance software development projects.
