👨‍💻 About Me

Computer Science (AI) student at the University of Nottingham Malaysia (Class of 2027) who ships systems that real people use — from production ERP platforms to medical imaging and site-safety computer vision.

  • 🤖 Final Year Project (in progress): an agentic AI order-fulfillment system — LangGraph orchestration + local LLM turning WhatsApp/email orders into validated ERP transactions, with safety-first guardrails (the LLM never decides stock, computes totals, or commits orders)
  • 💼 Part-Time Software Engineer @ Summit Company (M) Sdn Bhd — maintaining the 4 production ERP modules I built as a Software Engineer Intern (they kept me on after the internship)
  • 📄 First & corresponding author of an ML evaluation manuscript under review at Frontiers in Big Data — auditing benchmark contamination in an oral-health screening pipeline
  • 🥽 Built an AR site-safety system as a summer research intern — two internships, one summer
  • ☁️ Currently studying for AWS Certified Cloud Practitioner

🏆 Featured Projects

🥽 AR-PPE Detection

PyTorch YOLOv8 ONNX

AR site-safety intelligence: PPE detection at 98.2% mAP@50 (42k images), real-time AR overlay at ~57 FPS, and a custom identity layer lifting worker re-ID to 100% recall with 0% false merges even in identical PPE — up from an 8% baseline. Deployed to edge via ONNX + an installable phone app.
