There are some rules which any good freelancer will follow to succeed and land as many freelance coding jobs as he wants to.
Firstly, look at your job description and make sure it is specific enough for what the job offers. If you’re hired by a company that offers database development and design, make sure you mention that in your job description. It is necessary to state your skills needed in the particular industry in which you have to work. Some companies will use their keywords in the job description to help the recruiter weed out the undesirable.
Secondly, make sure that you use your skills to the best of your ability in your online freelance coding jobs. Avoid sending out resume after resume; just let them contact you personally via email or leave a comment on a blog related to the niche in which you want to work. This way, the remote developer or the hiring company will see that you have a real interest in the niche in which you have applied for the job, and they won’t be afraid to hire you.
