From 2018 to 2022, I was part of the core team at Rocketgenius, the company behind Gravity Forms, where I contributed to foundational features and built official add-ons for Stripe, PayPal Checkout, Mollie, and several CRM integrations. That experience set a high bar — shipping production code used by hundreds of thousands of sites means security, accessibility, and automated testing aren't optional. Working deep in the Gravity Forms ecosystem also gave me strong fluency in third-party API integration, from payment gateways to marketing platforms like Zoho CRM, Constant Contact, and HubSpot. I now run Shika Digital, a boutique WordPress engineering agency based in Tokyo, working with SMB clients across the US and Europe.

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.
