It took almost 5 months, but I'm finally done building the first public release of Spandraw.
I built Spandraw using React frontend, and Go backend, and I have found it to be a great choice to get things done with.
I started working on it after only having 9 months experience as a software developer, and I learnt a lot creating it. Building such a complicated app was definitely a bit ambitious. In hindsight, I should have targeted something simpler and got it out quicker!
