Customize a Wordpress Widget(s) for a Fitness website

I'm looking for a capable Wordpress developer who can help me customize 1-2 premium Wordpress plugin(s) for my fitness website. Both plugins are extremely developer friendly, including an extendable API and hooks for further integration into our theme and the WP Data Tables. The plugin will act as a our user's front-end CRUD system- allowing members to track their exercise and workouts. The plugins only need to be modified slightly to match the activity of our community. Most importantly, I'd like all development to be clean and user data to remain accessible via JSON and the WP REST API. Please see the attached images for further context. I look forward to speaking with you!
