Freelancer Overview

I am an AI Engineer with strong hands-on experience in building and deploying AI solutions that rely on high-quality data labeling and annotation, especially in computer vision and NLP domains. My work includes developing object detection systems using YOLOv8 and OpenCV for real-time ship draft measurement, as well as architecting chatbot and document processing pipelines with technologies like Python, LangChain, OpenAI, and FAISS. I have designed scalable data pipelines for text extraction, segmentation, and vectorization, ensuring efficient knowledge retrieval and accurate model training. My background in both generative AI and large language models has given me a deep understanding of the importance of precise, well-structured training data for robust AI performance, and I am adept at collaborating with cross-functional teams to optimize data workflows for production environments.

Ship Draft Measurement

LabelimgImageBounding BoxObject Detection

Designed and implemented a pipeline to process video frames, detect waterlines, and extract draft markings using YOLOv8 for object detection and character recognition. Developed algorithms to estimate the distance between the water contact point and draft markings, converting pixel-based measurements into real-world metrics (meters). Optimized the system for real-time performance, ensuring reliable operation under varying environmental conditions such as lighting and water surface reflections.
