Engineering perspective

Software is only
one layer.

I build applications with an understanding of the data, services, and hardware behind them.

My work spans a native Windows productivity application, an IoT forecasting system, and a QR-based attendance and allowance platform.

Personal project2026

AyOS

Personal Productivity OS

A native Windows application bringing productivity, finance, fitness, calendar, and automation into one offline-first system.

Tauri · Rust · React · TypeScript · SQLite · n8n

Engineering contribution

Built and shipped a React-to-Rust application with embedded SQLite. Validation, persistence, backups, and native operations live in Rust, with an authenticated localhost API connecting n8n workflows.

LINIS

Know which bin needs attention
before it overflows.

IoT System for Bin Time-to-Overflow Forecasting and Priority Collection

ESP32 · Raspberry Pi · Firebase · React Native · Python · YOLOv8 · Random Forest

Engineering contribution

Built a Random Forest forecasting model and a YOLOv8n people-counting pipeline using head detection within a defined region of interest. Synchronized sensor and camera data in real time and converted the vision model to NCNN for edge deployment.

    Raspberry Pi · YOLOv8n

    Head detection counts people within a defined region of interest. NCNN brings the model to the edge.

  3. 03

    Synchronize

    Firebase

    Sensor and camera data stay synchronized in real time.

  4. 04

    Forecast

    Python · Random Forest

    A Random Forest model uses the data to forecast bin fill levels.

QR Attendance
& Allowances

A QR-based attendance system that credits a predefined event allowance to eligible users after verified attendance.

Tailwind CSS · JavaScript · PHP · MySQL

Engineering contribution

Implemented dashboards for admins, workers, and attendees, with event management, attendance history, announcements, and allowance tracking. Validated core workflows through unit, integration, user acceptance, and performance testing.

  1. 01

    Create an event

    Define the event and its allowance amount.

  2. 02

    Verify attendance

    Record attendance through the QR-based workflow.

  3. 03

    Credit allowance

    Automatically credit eligible users after verification.
