Hi there, I am Arun πŸ‘‹

Linkedin Badge Gmail Badge

AI / ML Engineer β€” Generative AI Β· Machine Learning Β· Computer Vision πŸŽ“ Master of Applied AI (Deakin University) Β· πŸ“ Geelong, Australia

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

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

πŸš€ Featured Projects
