Job Success
Hyderabad, India - 5:07 am local time
I build production grade computer vision and live video analytics systems along with detection, segmentation, classification, tracking, and real-time inference that work in real-world workflows, not just notebook prototypes.
With 4+ years of experience across Machine Learning, Computer Vision, NLP, and Cloud AI, I develop systems that work with images, videos, live streams, and business data from data preparation and model training to production integration and deployment.
My Computer Vision work includes object detection, instance and semantic segmentation, classification, object tracking, automated annotation, and live video analytics using YOLO, YOLOv8, YOLOv11, PyTorch, Python, OpenCV, CVAT, and Roboflow.
I have built live video analytics pipelines that process incoming video streams, run computer vision inference on video frames, extract visual information, and generate analytics for downstream workflows. This includes real-time frame processing, detection and segmentation, tracking across frames, and video-based visual analysis.
On the Generative AI side, I build RAG systems, AI agents, enterprise knowledge assistants, conversational AI applications, and workflow automation using modern LLM technologies.
Recent production work:
98% Dice score on brain tumor segmentation (MRI) using U-Net, RAAGR2-Net, DeepLabV3, and SegFormer—from scratch in PyTorch (benchmarking for clinical accuracy).
95% accuracy car damage classifier deployed on VROOM Cars (production environment).
92% top-1 accuracy food classifier across 101 categories via ViT fine-tuning.
RAG chatbot that reduced support workload by 27% using PDF knowledge bases, ChromaDB, and FastAPI.
