Against Top IT professionals of the same age, you are making less than 50% of their salary.
Fresh grads (23) from Salesforce, Microsoft, Amazon, intel in Malaysia starts at 5k rm.
With the booming IT sector, easily 10k by 28 with not much effort.
But u are doing well for the rest of comparison. Just keep it up.
Next step would be to get a foreign paying job in Malaysia. That's way you get paid 30k a month while working in Malaysia. Not easy but doable

In IT it's not that difficult. Got one junior from my ex company, salary 6k+, June promoted to senior 7k+, one month later I got him through my current company interview offering 9k+, mana tau he was also interviewing another company, he rejected that offer saying he got 9k+ from mine, next day that company came out with new offer 10k+, so he went there.

Salary 6k to 10k in a matter of months yo. Not even 6 months.
