Just a couple of thoughts.
If you're aiming for small, non-tech-savvy local businesses, I suggest shortening both the headline and the paragraphs. Say less, and address their pain points directly ("My web apps will save you money. Here's how.")
Also, small business owners will likely not know what Github, AngelList, coderwall and such mean. You need to provide cases studies (perhaps with screenshots) and explain what you did, and how it increased revenue or saved money for your employers.
Lastly, are you tracking clicks on the Call To Action? How many visits are coming from your surrounding area? How can you increase that number?
Good luck!
