Hi, I'm Meng Han 👋
Aspiring AI/ML Engineer based in Singapore 🇸🇬.
Open to Work & Collaboration!
I'm actively seeking opportunities in AI/ML engineering and welcome collaborations on VLMs, LLMs, or real-world ML applications. Expecting to grad in Dec 2026.
My Journey
NUS Office of Internal Audit
AI Engineer Intern
- Built an end-to-end fraud detection system for vendor invoices using OCR, PDF forensics, and document similarity - cut manual audit time by ~30%.
- Designed an explainable unsupervised anomaly detector (Isolation Forest + SHAP) to flag suspicious claims without labeled fraud data.
Changi Airport Group
Machine Learning Engineer Intern
- Boosted taxi demand forecasting accuracy from 48% to 62% at Terminal 3 using XGBoost with time-series feature engineering.
- Automated flight turnaround analysis across 18k+ records to identify ground-crew bottlenecks and reduce departure delays
- Slashed monthly data pipeline runtime from 12h to 8.5h via a SageMaker-based ETL system with enhanced logging.
Cisco-NUS Accelerated Digital Economy Corporate Laboratory
Research Assistant
- Built a real-time human detection and tracking system using YOLOv8 + DeepSORT on overhead fisheye video feeds, achieving 84% mAP at 15 FPS on a standard workstation.
- Developed a low-latency pipeline to convert calibrated video streams into standardised JSON bounding boxes, enabling near real-time motion analysis for digital-twin applications.
Rockship (NUS Overseas College, Vietnam)
AI / Computer Vision Engineer Intern
- Created a RAG system (LangChain + LlamaIndex) that ingests 50+ n8n workflows to auto-generate new workflows
- Developed and deployed robust, scalable LlamaIndex RAG APIs for text and image embedding with built-in OCR safeguards, adopted as boilerplate by internal engineering team to accelerate prototype development
- Improved YOLOv8 nail detection mAP by 20pp via targeted labeling; integrated into an ARKit iOS app for sub-centimeter construction alignment
