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!

Yoren communicated clearly and was responsive and the result of the work is great. The biggest benefit was Yoren's understanding of what we would like to achieve and to propose the best-practice solution.

I have engaged pro consultants for over a month at cost with no progress in putting up my website, having wiped it 4 times because of conflicts. I now realize that many who know Wordpress do not know html or the hosting interfaces. Bluehost did a great job providing a starting website but I could not understand how to modify it. Yoren Change is a brilliant Engineer who easily understood and solved the issues including choosing billing and scheduling plugins to meet my current need and why changing, and figuring out where to edit in the plugins rather than the theme other than adding content. I originally was going to use woo but installed latepoint which gets me up and running. I used an Astra theme which is great but other plugins required manual wditing of the pre-setup links.
