Hi, I’m Ruslan Polyak.
Full-stack developer and business intelligence engineer with a strong foundation in JavaScript, Python, SQL, ETL pipelines, and Oracle APEX application development. I build practical, data-driven applications, automate workflows using modern data engineering tools, and experiment with machine-learning ideas—documented in my WIP section.

- AI-Automated S&P 500 black-box trading strategy research & experimentation
- Python open-source tooling:
- PDF document editor & formatter
- PDF data extraction pipeline → Excel/CSV exports
