Your ads look more like a sample of resume for job.
Write your ads, content focussing on whom you are targetting. Small business owner who may need your services, they may not even know name of any programming language. If you are looking to get response from other development firms who can hire you, who can outsource their work to you, then try google search suggestion tool to find keywords. Then write your ads again to match those keywords.
