Plugin Development
In 2018-2022 I had the privilege to work for Rocketgenius on the core features for Gravity Forms and add-ons like Stripe, PayPal Checkout, Mollie and other CRM integrations. I learned best practices to write secure code, add automated tests when possible, and make accessible software there. Building add-ons for Gravity Forms helped me enormously in understanding how to communicate with 3rd party APIs. Starting from some CRM/Marketing services like Zoho CRM, Constant Contact and HubSpot, I also specialized in several payment gateways. I currently work as an independent contractor with a focus on the plugin development sector. I have a more lengthy version of self introduction on my website: https://1fix.io/about/. Hope to see you there!
