About

Data Scientist with a strong mathematical background and experience building production machine learning systems in startup environments.

I help companies turn raw data into valuable products by developing machine learning models, automating data workflows and building reliable data pipelines in Python.

In my professional experience I have worked end-to-end on ML projects: from data strategy and labeling design to model development, deployment and monitoring in production systems.

I have also developed AI solutions using modern LLM frameworks such as LangChain and LangGraph to automate decision-making workflows combining structured and unstructured data.

Typical projects I can help with

• Machine learning models for prediction or classification

• Python automation and data workflows

• Data pipelines and ETL processes

• Web scraping and data extraction

• Data analysis and modeling

• LLM-based systems and AI workflows
