I'm a machine learning practitioner with experience in various data science competitions and real-world projects. I've been fortunate to work in image classification, time series analysis, and medical AI applications, and have had the opportunity to publish research papers and participate in AI competitions.
Currently, I'm building LLM Applications using LangGraph, focusing on:
- RAG (Retrieval-Augmented Generation) systems for knowledge-intensive tasks
- Workflow Automation pipelines powered by LLMs
- Multi-Agent Systems for complex problem-solving
I also have experience implementing deep learning model uncertainty and data drift monitoring for model lifecycle management in manufacturing environments.
