Thank you for your kind words about my article.
And now, lets respond to your question.
Actually, Medium is responsible for half of that. Yes, I've been writing on a regular basis for a few years. My efforts were rewarded handsomely.
And, while I do have a 9 to 5 job, I haven't mentioned it in this post because this is all about side hustles. To be honest, since I work as a web developer and also write on Medium, I've been able to secure some extra contract or consulting work.
Assume some companies see my Medium article and contact me through email or LinkedIn to discuss future opportunities.
I hope you received your answer :)
