Hiya @Zaynab
We have a section in our expat guide on Singapore explaining how to look for work. You should have a look.

 

I must be a bit difficult with sport and fitness currently with the covid restrictions. You should post you CV in our specific section and describe your search (short statement on the Job search in the form) here: https://www.easyexpat.com/en/job-offers/singapore.htm

Best of luck and feel free to share your findings and situation in this topic.
