wonghanz/README.md

Wong Hanz — Systems and AIoT Engineer. Universiti Malaya, Penang Malaysia. Swift, Kotlin, Python, ESP32, LLM pipelines, distributed systems.

I build systems that stay up — sensor to socket to screen.

Native mobile, embedded telemetry and agentic AI pipelines for real deployments in Penang and Kedah. Not prototypes: things commuters, farmers and students use.

Selected work

Six systems I designed and shipped. Open-source cards are clickable; the three client projects are proprietary and labelled as such.

Eloquent Lab — native iOS and Android exam-prep SaaS. 100+ MAU, 90 percent faster grading, zero ad spend. SwiftUI, Jetpack Compose, RevenueCat, DeepSeek. NodiGuard — zero-trust local AI proxy for coding agents. Leaked API key interception, local prompt tokenisation, 16 GB VRAM purge. Python, TLS, Ollama, Linux.
PlantX and RHISS — agricultural telemetry and redundant power control. 30 percent less water, 50 percent faster growth, Petrosains partnership. ESP32, MicroPython, sensor fusion. CapriGuard — livestock AIoT platform on a 300-head farm. RFID edge units, automated health triage. PHP, ESP32, REST, Gemini API.
Transit Booking — seat selection and payment for Terminal Shahab Perdana. 300+ DAU, Fiuu and FPX checkout, QR boarding passes. Kotlin, Swift, offline-first. Liquid Glass on iOS — refraction shaders backported across iOS 13 to 18 for a Telegram fork. This profile's design language came out of this project. Swift, Metal, Core Animation.

Where I am

Where I am. Nested reach: Bayan Lepas Penang is the home base where field hardware is built and tested; Penang and Kedah carry live deployments across a transit terminal, a livestock farm and exam-prep classrooms; Malaysia covers the RM 100,000 Cradle CIP Spark grant architecture and placing first of 18 national matriculation colleges; Southeast Asia covers the EcoRise SEA Challenge 2026 championship and four gold medals abroad since 2023. Current position: Lead Mobile SaaS and Growth Engineer at Eloquent Lab, remote. Before that AI Engineer and Grant Research Lead at IoT Services Sdn. Bhd. Studying B.Sc. Computer Science at Universiti Malaya, expected 2030, with a flat 4.00 CGPA and MUET Band 4. Head Peer-Assisted Learning Supremo and PAL Chemistry Lead at KMKK, where I trained 40+ peer educators, built the PAL ExScience research-first method, turned abstract chemistry concepts into interactive AI-built modules, and led the college to number one of 18 Malaysian matriculation colleges with 480 of 485 students scoring an A. President of the Robotic and Innovation Club at SMJK Heng Ee. Founded STEMgineers Club at KMKK, training 100+ members and mentoring 20 gold-medal teams. Learning real-time DSP for speech scoring and local-first inference. Reach me at wonghanz2007@gmail.com, open to systems and AIoT roles and research work.
