Customizations, Plugin Development, Troubleshooting and Fixes
Checkout broke after an update and nobody can say why? Orders sit in pending, a payment plugin works in testing but fails for real customers, or an API sync quietly drops orders? That's the work I take on. I'm a senior WooCommerce engineer, and clients bring me in for the jobs that are expensive to get wrong. What I can help with - Checkout and payments: Stripe, Square, PayPal Braintree, webhooks, refunds, orders stuck in pending - API integrations: connecting WooCommerce to POS, accounting, CRM and AI services - Custom plugins and extensions, or cleaning up plugins that were edited in place - Slow product, cart and booking pages (one booking page went from 3.8s to 1.1s) - Upgrade audits for PHP, WooCommerce and checkout blocks, before they break custom code Background At 10up (now Fueled) I worked on official WooCommerce extensions built with the WooCommerce team, including Square, Bookings, Box Office and Xero, and before that at Multidots on enterprise WordPress sites. - Credited in 13 WordPress releases (5.1 to 7.0) - 300+ merged pull requests across WooCommerce core and 15+ official extensions - Lead contributor on Simple Local Avatars (100,000+ active installs) How I work I read the code before I quote. You get a written scope: what I'll change, what I won't touch, and why. Fixes are tested on staging first, follow WordPress coding standards, and come with notes your team can maintain. For an accurate estimate, include: - What's going wrong and when it started - Steps to reproduce, or a screenshot of the error - Which plugins are involved (payment gateway, checkout, shipping) - Whether you have a staging site I'm based in India (UTC+5:30) and work with clients in the US, UK, Europe and Australia, with daily overlap.

Faisal is a developer I would recommend to anyone. He clearly understood what advise I was seeking. Faisal then went to work implementing a thorough agreed-to scope within his original mandate, which included making recommendations to remedy 20 additional website issues I did not know I had. Upon completion, he further recommended and executed key scope items he would fix, if he were me. Faisal is very experienced, thoughtful, articulate & very experienced; exceeding all my expectation.

WordPress Core contributor, credited in 13 releases
Patches, bug reports and testing for WordPress core, credited in 13 releases from 5.1 to 7.0. Also a contributor to Simple Local Avatars (100,000+ active installs) and Publisher Media Kit on WordPress.org, and support rep for 20 open-source plugins.
Simple Local Avatars: lead contributor (100,000+ installs)
Lead contributor to 10up's Simple Local Avatars, a WordPress.org plugin with 100,000+ active installs that lets users upload avatars locally instead of relying on Gravatar. 44 merged pull requests across features, bug fixes, compatibility and releases.
Accessibility fixes across official WooCommerce extensions
Accessibility (WCAG) fixes and code reviews across official WooCommerce extensions, including AutomateWoo Refer a Friend, Pinterest for WooCommerce, WooCommerce Bookings, Accommodation Bookings and Box Office: keyboard operability, accessible booking datepickers and calendars, and audit findings, confirmed in the browser before review.
Membership site: card updates failing silently, fixed
Customers updating their card sometimes hit a dead error page with no clear pattern. I reproduced a timing race between the membership plugin and a late-loading payment script, then shipped a small guard plugin with a retry path instead of a rewrite. No repeat failures since launch, and the client moved to an ongoing maintenance plan.
WooCommerce store: no shipping options and zero tax, fixed
A store charged no tax on any order and could not ship internationally. I traced it to three conflicting plugins and a dead API key, removed the conflicts, configured tax natively, built shipping zones and backfilled product weights. The store now gets accurate international shipping rates and tax on every order.
Jobber for WordPress: forms and online booking plugin
WordPress plugin for Jobber, the field-service platform, that lets service businesses embed Jobber request and online booking forms with a block. I own the WordPress side: block editor experience, REST endpoints that talk to Jobber's API through a middleware, response caching and Cypress tests.
