👋 Hi, I'm Sudharsan

🎓 Artificial Intelligence & Data Science Undergraduate | 💻 AI/ML Developer | 🔬 Computer Vision & LLM Enthusiast

I specialize in building AI-powered applications that bridge the gap between research and deployment.
My work spans computer vision, natural language processing, large language models, and applied machine learning,
with projects that demonstrate end-to-end system design — from training deep learning models to deploying full-stack AI solutions.

I’m a strong believer in ethical AI and the value of creating resource-efficient, local-first solutions such as offline LLMs and lightweight CV pipelines.
Beyond academics, I’m constantly experimenting with generative AI, similarity search, re-identification, and real-time video analytics, always focusing on real-world utility.
