## About

🚀 I’m a Machine Learning Engineer with a deep curiosity for solving real\-world problems through AI\. With an M\.E\. in CSE from Jadavpur University and a 91\.25 percentile GATE CS '22 rank, I combine academic rigor with hands\-on engineering\. 💡 I specialize in LLMs, RAG systems, GANs, and deep learning pipelines—developing solutions like a medical domain RAG chatbot using LangChain \+ Ollama, and a GAN\-based underwater image enhancer that achieved PSNR: 23\.06, SSIM: 0\.7182, and FID: 39\.45\. 🛠️ Skilled in Python, PyTorch, TensorFlow, FAISS, and LangChain, I thrive in building ML products from ideation to deployment\. I enjoy working on generative models, retrieval\-augmented generation, and multimodal learning\. 🎯 Now actively seeking full\-time opportunities in AI/ML, where I can build intelligent systems, collaborate with great minds, and keep learning every day\. Let’s connect if you’re looking for someone who’s ready to push boundaries with AI\.
