I will develop a custom wordpress or woocommerce plugin, or fix your existing plugin
Anantoni
About this gig
Custom WordPress and WooCommerce plugin development by a senior engineer and PhD researcher in program analysis. Need a feature WordPress doesn't have, or a plugin that's broken? I write clean, secure, documented plugins that follow WordPress coding standards.
What I build: custom post types and fields, booking and form tools, WooCommerce add-ons, Stripe/CRM/Google Sheets/REST API integrations, Gutenberg blocks, admin settings pages, plus performance and security fixes to existing plugins.
How I work: a standalone plugin (no theme edits, so updates can't break it), tested on the latest WordPress and PHP, with nonces, capability checks and escaped output. You get the full source code and a short how-to.
Why me: papers at OOPSLA, PLDI and ECOOP on how programs behave; I built and run almanauts.com (18,000+ pages, CI/CD deployment); I ran a WordPress site with my own business for two years. I use AI coding agents for speed and review every line myself.
Message me with what you need. I usually reply the same day.

FAQ
Will the plugin break when WordPress or my theme updates?
No. I build it as a standalone plugin that follows WordPress coding standards and uses core hooks, so theme and core updates don't wipe or break it. I test it on the latest WordPress and PHP.
Do I get the source code?
Yes. You own the full, documented source code, with no licence keys or lock-in. I can also hand it over as a Git repository.
Do you use AI tools?
Yes, for speed: I run AI coding agents, then review and test every change myself before delivery. If your project forbids AI tools, tell me and I'll follow your rules.
