Custom WordPress membership and events platform / Membership community

Sisters on the Fly Membership Platform

Modernizing the events, payments, data, and application infrastructure behind an active membership community.

Sisters on the Fly

Project Overview

Sisters on the Fly uses a highly customized WordPress platform to support a membership community, public content, event activity, payments, uploaded media, and data used by a companion application.

End Everything Studios supported ongoing development and modernization inside that active system, preserving existing workflows while repairing legacy code, strengthening integrations, and clarifying how member, event, payment, media, and application data fit together.

The Challenge

The work took place inside an active, interconnected legacy platform rather than a clean rebuild. Member accounts, event records, payment activity, uploaded images, custom tables, AJAX handlers, and app-facing data all depended on one another.

That meant changes had to be made carefully, with attention to backward compatibility, production data that continued changing, and features that could not be interrupted while modernization work moved forward.

What We Delivered

Legacy Platform Modernization

Custom PHP and WordPress functionality was reviewed, repaired, and updated for newer environments while avoiding a high-risk full-platform rewrite.

Stripe and Membership Workflows

Payment-related functionality and Stripe webhook handling were reviewed and rewritten where needed so membership activity could be processed more reliably.

AJAX and Application Data

Browser-to-server interactions were debugged around structured requests and JSON responses, with attention to data also required by the companion application.

Database and Media Architecture

The work clarified how users, events, payment records, uploaded images, and application data were connected so future migration and modernization work could be planned safely.
