http://steemtools.com is a good place to start. There are API's and other tools that could help. Also, https://github.com/steemit would be good to check out. You can do a google search as well to find posts that can help you.

One last thing I would suggest is to get on https://steemit.chat/ and Discord communities where you can communicate with others users that could help. Feel free to message me on Discord or here on Steemit if you need any more help.
