I'm an AI/ML Engineer based in Hyderabad, India, specializing in building production-ready intelligent systems. My work spans retrieval-augmented generation (RAG), computer vision, medical imaging, and end-to-end ML pipelines—from data processing to deployment.

• 🔬 Deep Learning Research: Medical imaging, OCT retinal disease classification, liver segmentation
• 🤖 GenAI & LLMs: RAG applications, agentic systems, prompt engineering, fine-tuning (LoRA, full)
• 🏥 Healthcare AI: Diagnostic models, biomedical NLP, AI-driven healthcare solutions
• 📊 ML Engineering: Data pipelines, model evaluation, API development, cloud deployment

Data → Processing → ML/DL → Retrieval/LLM → Evaluation → API → Deployment

• IIT Madras Road Safety Hackathon Winner — ₹7.5 lakh grant for an AI-driven bike-safety enhancement system that identifies rash driving and potential falls, then alerts through a phone. Read the coverage

DevOps, Cloud & Tools

• Architected a retrieval-augmented agent using LangChain with filtering, grounding, and multi-turn memory
• Integrated GPT-3.5 Turbo via API workflows — reduced average query cost by 10%
• Designed end-to-end ML pipelines: preprocessing, feature engineering, training, evaluation, and scikit-learn model deployment

• Built sEMG acquisition pipeline + LSTM for lower-limb abnormality detection (67% diagnostic accuracy)
• Pneumonia detection with MobileNet-V3 transfer learning — 94% accuracy, with Grad-CAM explainability
• Dockerized Django application deployed on AWS EC2

• Developed an MLP Mixture Model for retinal disease classification using Optical Coherence Tomography (OCT) images
• Achieved 98.4% accuracy, driving diagnostic precision in ophthalmology
• Tackled class imbalance through weighted loss functions, improving generalization and robustness for real-world healthcare deployment
• Applied advanced deep learning and computer vision methods to enhance diagnostic models

• Designed and optimized U-Net and Half U-Net architectures for precise liver segmentation
• Achieved 97.6% IoU and 9.4% Dice Coefficient, setting new standards in medical imaging accuracy
• Developed and tested custom loss functions to improve model performance
• Gained hands-on experience with AWS, Docker, and GPU-based cloud services (including NVIDIA A100 GPUs) to accelerate model training and deployment

RAG LangChain LangGraph ChromaDB Agentic AI LLM

A retrieval-powered FAQ assistant built for grounded Jupyter-related answers. The pipeline processes documentation, extracts FAQs, creates persistent embeddings, retrieves relevant context, and produces source-aware answers with agentic reasoning.

• Built an agentic RAG system with filtering, grounding, and multi-turn memory

• Used LangChain and LangGraph for orchestrating retrieval and generation workflows

• Implemented category-aware retrieval and citation-backed answers
