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.

What I’m working on

  • Next.js + Tailwind site refresh
  • 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
