When you need a custom plugin

A custom plugin is the right answer when:

no plugin in the directory does what you need, or the closest one does ten things you don't want
you've customized a third-party plugin and now can't update it
business logic lives in your theme's functions.php and would disappear with a redesign
you need to connect WordPress to an internal system or API

Putting logic in a plugin, not the theme, keeps it portable. You can redesign the site without rebuilding the functionality.

What I build

Automation plugins: scheduled imports, syncs and clean-ups. Example: a YouTube import plugin that keeps a site's video library in sync with a playlist, with no manual publishing.
Content-structure plugins: new content types with their own admin UI. Example: a release notes plugin in use for 2+ years with zero reported issues.
WooCommerce extensions: custom pricing, checkout fields, order statuses and quote flows. See WooCommerce development.
Integration plugins: connecting WordPress to CRMs, ERPs and SaaS tools. See API integration.
Plugin rescue: taking over an abandoned or broken custom plugin, stabilizing it and documenting it.

How I build plugins

✓Object-oriented PHP 8 with namespaces and Composer autoloading
✓WordPress Coding Standards (PHPCS) enforced
✓Security by default: capability checks, nonces, sanitization on input, escaping on output, prepared SQL
✓Settings pages built on the Settings API or ACF options
✓Background jobs with Action Scheduler for anything slow
✓Logging and admin notices so failures are visible, not silent
✓Clean uninstall routines that don't leave junk in your database
✓Translation-ready (i18n) when needed

Typical project types

✓Import/sync plugins for external data sources (APIs, CSV, feeds)
✓Custom WooCommerce product types and pricing rules
✓Form-to-CRM connectors (see WPForms → Zoho CRM)
✓Admin tools such as bulk editors, exports and reports
✓Replacing a paid plugin with a lean custom version

Questions I get asked

How much does a custom WordPress plugin cost?

Small, single-purpose plugins are a fixed-price project, usually 2–3 weeks from start to handoff. Integrations and multi-screen admin tools take longer. You'll get an exact quote after a short scoping call. Starting ranges are on the pricing page.

Will you publish the plugin on WordPress.org?

Only if you want it public. Most client plugins stay private and are installed directly on your site.

Can you fix a plugin another developer built?

Yes. I start with a code review, then stabilize the most critical issues first.

Will the plugin slow down my site?

It shouldn't. I load code only where it's needed, cache expensive lookups and move heavy work to background jobs. Performance is checked before handoff.
