The 90,000+ install form builder where my career began: premium add-ons, new fields and integrations.
Everest Forms is where my career started. I joined ThemeGrill as an intern with no WordPress background, began working on this plugin after a few days of training, and stayed on it for about a year as a Junior PHP Developer.
I built many of its premium add-ons: Authorize.Net payments (one-time and recurring), Razorpay, discount coupons, Amazon S3 and OneDrive storage for uploads, PDF submissions, and integrations with Zoho CRM, Sendinblue, Constant Contact, Drip and GetResponse. I also added new field types (colour, payment slider, progress, subtotal and yes/no), along with webhooks, email whitelisting, usage tracking, per-form settings and entry exports in several formats.
