Portrait of Oleksa Tyshchenko

What I have built

  • A low-code platform

    Owned the frontend architecture of that platform: a widget system configured at runtime.

  • AI in production

    Took LLM features from prototype to production, inside real product flows, not a demo chatbot.

  • A language and its editor

    Designed the DSL behind a low-code reporting platform, so analysts could write their own formulas instead of filing tickets.
