spent some time learning Kotlin (Java was very verbose) and JVM dev environment
made feature parity with the TypeScript version. This time project, UX felt like magic as forwarding was instant.
started web interface
My original specialization is Front-end, so here I felt a real flow. I tried to use some external component libraries on top of React to built UI. But I mostly ended up implementing my components.
Any way this phase took a long time as building interfaces is not a fast process. I spent around 500 hours on UI.
