KomuraSoft LLC works on web development and app development. Alongside that, we publish easy-to-follow learning materials across a wide range of technical fields — not only IT, but also mathematics, information theory, communications, control, chemistry, and energy.

Technology is not reserved for a narrow group of specialists; it is part of the foundation of society. The more people who can touch, understand, and use it, the higher the overall technical capability of the country rises.

How the courses are designed

  • Start with a diagram so the whole picture lands before the math — beginners do not get lost.
  • Only the equations that actually matter, so you can work through the key points by hand.
  • No installation needed: everything runs in the browser and is ready to try immediately.
  • Answers and progress are stored only in localStorage and are never sent to a server.
