Custom WordPress Plugin
When off-the-shelf plugins don’t fit — I build exactly what you need.
Let's Fix ThisThe Problem
You've searched the plugin directory. You've tried the premium options. Nothing does exactly what you need, or worse, you're using three plugins duct-taped together with custom CSS hacks. You need a single, clean plugin built specifically for your use case — one that doesn't bloat your site, conflict with other tools, or break on every update.
I've built WordPress plugins ranging from the WooCommerce Auction system (162 features including real-time bidding, proxy bids, and anti-snipe) to focused utility plugins like the geo-currency plugin that auto-detects visitor location and switches displayed currency, and the bulk product edit plugin that lets store owners update thousands of products from a spreadsheet-like interface. Every plugin I build follows WordPress coding standards — proper hook usage (actions and filters), sanitization and escaping on all inputs and outputs, nonce verification on forms, capability checks on admin pages, and prepared statements for database queries. This isn't just best practice; it's what prevents your site from getting hacked. The architecture uses object-oriented PHP with proper namespacing, keeping the plugin isolated from conflicts with other plugins. For plugins that need a frontend interface, I build with vanilla JavaScript or React (using the WordPress @wordpress/scripts build pipeline) depending on complexity — avoiding jQuery dependency since WordPress is moving away from it. Admin interfaces use the Settings API for simple options or custom React-powered panels for complex configuration. I also handle the WooCommerce-specific requirements that trip up most developers: proper HPOS (High-Performance Order Storage) compatibility, block-based checkout support, and compatibility with the site editor. Every plugin ships with inline documentation, an admin help section, and a README that covers installation, configuration, and troubleshooting.

What You Get
Frequently Asked Questions
Will the plugin break when WordPress or WooCommerce updates?
I build against the official WordPress and WooCommerce APIs using documented hooks and filters — not internal functions that change without notice. I test against WordPress beta releases before major updates. With a maintenance plan, I proactively update the plugin when breaking changes are announced in upcoming releases.
Can the plugin be listed on the WordPress plugin directory?
Yes, if that's your goal. I build to WordPress.org submission standards including proper readme.txt formatting, screenshot preparation, and compliance with their plugin guidelines. I handle the submission process and address any reviewer feedback. For commercial plugins, I can also set up licensing and update delivery infrastructure.
Do you provide ongoing support and updates for custom plugins?
Yes. I offer maintenance plans that include WordPress and WooCommerce compatibility updates, bug fixes, and minor feature additions. The plugin code is yours — you own it completely. If you want to bring maintenance in-house later, I provide a thorough developer handoff with architecture documentation and code walkthrough.
Can you extend an existing plugin instead of building from scratch?
Often, yes. If an existing plugin does 80% of what you need, I can build a companion plugin that extends it via hooks and filters rather than modifying the original. This is faster, cheaper, and won't break when the base plugin updates. I evaluate this option first before recommending a full custom build.
