✍🏻 The drawing app to express, grasp, and organize your thoughts and ideas. Draw to explain. Draw to grasp.

Hi there!

I'm Oleksii. I work as a full-time software engineer at Uber. In my spare time, I do open-sourcing.

Most of my open-source 🚀 projects below 👇🏻 are focused on one thing - to help people learn 📚. You may use these projects to learn about algorithms in JavaScript and get prepared for technical interviews, or to learn Python syntax and start experimenting with machine learning algorithms and the math behind them, etc.

There are also other projects that I've developed for fun but that you might find useful, like ✍🏻 okso.app online drawing app.

I also write 📝 articles about life, web development and machine learning.

okso-app's Issues

Exported PNG/JPG shows all black

First of all, I want to thank you for such a wonderful program.

See https://pixey.org/p/mandarvaze/512542286449385052
This looks OK because I have used purple color for the text. So it looks OK in either black background or white

On the other hand : https://pixey.org/p/mandarvaze/508073589008507776 looks all black in full view mode. It looks OK on the profile page in a thumbnail view. This is a face of a man.

I tried this in Chromium, MS Edge and Firefox (all on macOS)

This may be because there is no background.

Curved arrow missing

The fixed point of a state machine is a state that stays the same.
This is indicated by a curved arrow that returns to the circle it came out of.

How to share my draw screen?

I have draw some patterns and want to share my team.
How can I do that.
