Build Zapier JSON API for my application

I am looking for someone with experience with Zapier to develop a JSON API for my application. This will be a custom private project, I will want to create actions and triggers on my personal application which I can then integrate with the 100's of applications that are available in Zapier. I will need about 25 actions (new signup, user login, user login by plan, trial expiration, cron job performance, etc). Some of the actions will be from webhooks from Stripe. Please bid only if you have done something similar before with Zapier.
