Hi there, I am Arun 👋

Linkedin Badge Gmail Badge

AI / ML Engineer — Generative AI · Machine Learning · Computer Vision 🎓 Master of Applied AI (Deakin University) · 📍 Geelong, Australia

I build and ship ML systems end-to-end — from real-time computer vision on edge GPUs to agentic, RAG-based LLM applications with LLMOps tooling. Currently focused on production GenAI.

  • 🔭 Building a public GenAI portfolio — RAG, agentic AI, and LLMOps
  • 🌱 Going deeper on LangGraph agents, RAG evaluation, and MLOps
  • 💬 Ask me about computer vision on NVIDIA Jetson, RAG pipelines, or LLM apps
  • 🚀 Open to mid-level GenAI / ML / MLOps roles in Australia (full working rights)
