I have a live WordPress site that now needs a round of deep-level enhancements. Your main focus will be on custom plugin work and building out new functionality powered by Advanced Custom Fields (ACF). The theme is already in place; what I need is clean, modular code that slots into the existing stack without bloat, keeps the database lean, and respects WordPress best practices. Here is the broad outline of what I expect: • Extend or create one or more custom plugins to deliver the new features I will detail in a shared spec document. • Structure every new data point with ACF so content managers can work from the back-end intuitively—no hard-coding options. • Follow modern WordPress standards: namespaced PHP, proper hooks and filters, enqueueing assets correctly, and preparing the site for easy future updates. • Maintain site performance. Any queries you write must be optimized; any front-end output must respect the current design system and remain lightweight. • Document your code and provide a clear hand-off guide so another developer can pick things up without detective work. Acceptance criteria 1. All requested features run through a standalone plugin (or plugin suite) and can be activated/deactivated without breaking the theme. 2. Every custom field group is configurable through ACF and reflects exactly the data structures in the spec. 3. No console errors, no PHP notices, and Lighthouse performance scores remain within 5 % of their current baseline. 4. A concise changelog and installation notes accompany the final delivery. If you thrive on precise requirements, write tidy code, and can turn around polished solutions quickly, I’m ready to share the repo and full task list.
