🧠 About

I am a Computer Science Engineering student at KIT – Kalaignarkarunanidhi Institute of Technology, Coimbatore, specialising in Artificial Intelligence, Computer Vision, and Machine Learning. I design and deploy real-world intelligent systems β€” from microplastic detection with YOLOv8 to precision agriculture platforms integrating aerial drones and IoT sensing.

My engineering philosophy centres on building systems that are accurate, scalable, and purposeful. I have validated this through national-level hackathon victories β€” winning β‚Ή25,000 prizes twice and placing 4th among 435+ teams at the TNWISE State Hackathon. I bring a strong foundation in deep learning, LLM fine-tuning, and full-stack prototyping, complemented by hands-on experience with PyTorch, OpenCV, Raspberry Pi, and cloud-based analytics dashboards.

  - AI / ML Engineering Internships
  - Research Collaborations (Computer Vision, Environmental AI)
