One of my coworkers is doing this: wake up early at about 6am, work till 4pm = 9 hours with a lunch break and commute.

After he comes back home, he spends time with his gf watching tv but still coding for another 2 hours at least.

This way he can work 220 hours a month not counting his side projects he works on weekends/free time.

He is easily pulling about 250-260 hours a month.

Yes, he's a workaholic.

Yes but you can use your advantages. It's only about finding the right opportunity.

I don't mean to be intrusive, but how much can one earn after this experience?

All depend of your location of course. I live in São Paulo, Brazil. I earn 4500 Reais per month (~ 1300 usd per month). This is actually around 30% higher than what I was expecting as an average salary for a junior web developer. Luckily I landed the job with the highest pay.

My expectation is to double that within two years. I believe my former work experience can accelerate my path to be a senior developer. And then keep going on a more linear growth.

Awesome, thank you. I wish you good luck!
