About this platform

A working notebook for engineering practice

This is Mostafa Effati’s personal engineering platform: a place to turn hands-on work into clear writing, structured learning, and useful digital products.

Student collaborator

  • Ms Zahra Ehsani

    Former student · platform contributor

    Ms Zahra Ehsani worked on parts of this platform during her studies and brought thoughtful, practical contributions to its development. I'm glad to recognize her work here.

What you will find

  • Long-form articles, books, tutorials, and practical snippets.
  • Courses and guided learning paths built around real engineering work.
  • Case studies, open-source work, experiments, and product releases.

Built deliberately

  • A bilingual Persian and English experience with native RTL support.
  • Theme-aware, keyboard-friendly interfaces with a focused visual language.
  • Content and product changes developed as one versioned system.

The platform is continuously evolving. Some sections are complete products; others are active experiments that improve as the underlying work develops.
