SLSY-2026 · REV A · COMPUTER ENGINEERING
Embedded-systems engineer moving up the stack — from bare-metal C to on-device AI.
GENERAL DESCRIPTION
Stanley Lin is a National University of Singapore Computer Engineering freshman (2026) and Singapore Polytechnic graduate (2024, GPA 3.80/4.00). He builds systems that operate under hard constraints: bare-metal firmware with no OS, on-device AI with no internet, and industrial automation under safety requirements. His work spans PIC18F4550 microcontrollers and IIoT edge deployments at A*STAR ARTC to an offline RAG pipeline for the Republic of Singapore Navy. Outside engineering, he founded Convenient Oasis, an e-commerce venture he ran single-handedly — supplier sourcing, a Shopify storefront, and ACRA business registration.
FEATURES
Offline Android clinical-reference app for the Navy Medical Service — on-device Gemma 3 1B RAG chat for Medical Officers, deterministic protocol search for medics, zero connectivity required.
| Platform | Android — model and vector database entirely on-device |
|---|---|
| Model | Google Gemma 3 (1B parameters) via MediaPipe LLM inference |
| Base | Built on Google's MediaPipe RAG Android sample |
| Retrieval | Hierarchical parent-child chunking — 1000-char parents, five overlapping ~250-char children |
Top-down factory collision-prevention system — custom-trained YOLOv8n detects humans and robots through an IP camera, with bounding-box overlap logic raising collision warnings.
| Dataset | Custom top-down dataset — 1,612 person + 2,132 robot usable instances (2 robot types + human mannequin) |
|---|---|
| Model | YOLOv8n (nano) — custom-trained |
| Detection | Top-down IP camera view; bounding-box overlap triggers collision warning |
| Role | R&D Engineer Intern — A*STAR ARTC |
Bare-metal C sleep-environment automation on PIC18F4550 — dual-RTC timekeeping over I²C, two-sensor activation logic, and a five-stage escalating wake alarm.
| MCU | PIC18F4550 |
|---|---|
| Toolchain | MPLAB X IDE / XC8 C Compiler |
| Peripherals | DS1307 RTC (I²C), 20×4 LCD, 4×4 keypad, PIR sensor, LDR, USB aromatherapy diffuser, buzzer |
| Context | Singapore Polytechnic — MAPP module |
JavaFX desktop wellness tracker with Harris-Benedict-based daily targets, gamified quiz and badge rewards, and a SOLID-structured OOP design — later migrated from local MySQL to Huawei Cloud RDS for the Huawei Developer Competition APAC 2023.
| Platform | Desktop — JavaFX with FXML and CSS |
|---|---|
| Database | MySQL 8 — migrated to Huawei Cloud RDS with Elastic IP binding |
| Targets | Harris-Benedict equation for personalized calorie, exercise, and sleep goals |
| Design | MVC + SOLID — separated DB handler, calculator, and validator classes |
| Organisation | Role | Period | Outcome |
|---|---|---|---|
 Republic of Singapore Navy | R&D Engineer (NS) | Oct 2024 – Aug 2026 | Built AidBuddy — offline on-device RAG clinical decision support for naval medics; scaled at DSTA MedXplore Hackathon |
 A*STAR ARTC | R&D Engineer Intern | Sep 2023 – Feb 2024 | Developed YOLOv8 robot-human collision prevention; led IIoT edge computing deployment achieving 50% latency improvement |
 Singapore Polytechnic | Research Assistant | Mar 2024 – Jul 2024 | Managed DL vision model research; built Python monitoring dashboard; authored NLP lab materials; packaged models as single-file executables |
 Convenient Oasis | Founder | Late 2024 | Sourced suppliers, built the Shopify storefront, and registered the business via ACRA for a US outdoor-hydration brand |
