WooCommerce & PHP Systems Developer

Samurai Fireworks sees its highest traffic during the July 4th season, but checkout was painfully slow — sometimes 8–10 seconds to load the cart and payment pages. Customers were abandoning before completing purchase. The store ran dozens of plugins with no object caching, and the WooCommerce admin was unusably slow during peak days.

I performed a full WooCommerce audit using Query Monitor and server logs. I found N+1 queries in the cart session handler, unoptimized product meta queries, and blocking external API calls during checkout. I implemented Redis object caching via wp-redis, rewrote the problematic cart hooks, deferred non-critical external calls to WooCommerce's action scheduler queue, and removed conflicting plugin combinations.

Checkout page load dropped from 8 seconds to under 2. Completed order rate increased 18% in the first season after the fix. The WooCommerce admin became usable again and the team could manage products during peak traffic without timeouts.

The Our Tiny Garden team received CSV files from their plant supplier each morning with updated stock counts and pricing. A staff member spent 2–3 hours every morning manually updating each product in WooCommerce. Errors were common — overselling out-of-stock plants was a regular occurrence, leading to customer complaints and refunds.

I built a custom WordPress plugin that automatically fetches the supplier's CSV feed via FTP on a scheduled WP Cron job. The plugin parses the CSV, maps supplier SKUs to WooCommerce product IDs, updates stock quantities and prices, logs any unmapped SKUs for review, and sends a daily digest email to the store owner summarizing all changes made.

The daily manual process was fully automated. Staff no longer spend time on inventory data entry. Overselling dropped to near zero. The store owner gets a daily email showing exactly what changed — and can override any sync result directly in the WooCommerce product editor.

WebReady Now is a web agency managing 40+ client websites. They were spending hours each month manually pulling Google Analytics and PageSpeed data into custom PDF reports for each client. Clients kept asking for more frequent updates. The team wanted a way for clients to view their own data without needing Google account access or waiting for a monthly report.

I built a custom WordPress plugin that adds a front-end client portal to the agency's WordPress site. Each client gets a unique login and dashboard. The plugin uses the Google Analytics Data API (GA4) and Google PageSpeed Insights API to fetch data per client, caches results in transients to avoid API rate limits, and displays clean dashboards with traffic charts, Core Web Vitals scores, and performance trends over time.

The agency eliminated their monthly PDF reporting process entirely. Clients now check their own dashboards on demand. Client retention improved — clients who used the portal regularly renewed at a higher rate. The agency now offers portal access as a paid add-on to their monthly retainer plans.

Beghelli USA runs a B2B WooCommerce store for commercial lighting products alongside their internal ERP system. Product data, pricing, and inventory lived in the ERP — but staff had to manually re-enter changes in WooCommerce. Orders placed in WooCommerce also needed manual ERP entry. The two systems were chronically out of sync, causing order errors and overselling.

I built a custom WordPress plugin that acts as a sync bridge between their ERP's XML API and WooCommerce. Products and inventory flow from ERP to WooCommerce on a scheduled 15-minute sync. New orders flow from WooCommerce to ERP immediately via webhook. The plugin includes an admin log panel to review all sync events, flag errors, and manually trigger re-syncs for specific products.

Manual data entry between systems was fully eliminated. Product catalog accuracy reached near 100%. New orders appear in the ERP within seconds of being placed. The admin team now uses the WooCommerce dashboard as their primary interface with full confidence that ERP data is always in sync.

Dealer users needed access to updated product information — name, SKU, retail price, dealer price, stock level — without manual back-and-forth.

Built a custom WooCommerce export workflow that generates secure CSV product data for dealer users with role-based access.

Reduced manual work, improved dealer access to product data, and created a more efficient business workflow.

An auto dealership's WooCommerce website listed their vehicle inventory. The dealer management system (DMS) exported a full inventory CSV daily. Staff had to manually import, update, and remove vehicles — a 2-hour process every morning. Vehicles that sold were still showing online for days. New arrivals took days to appear after arriving on the lot.

I built a custom WP plugin that fetches the daily CSV from a secure FTP server, parses vehicle data (VIN, year, make, model, trim, price, mileage, status), and performs a full diff against existing WooCommerce products. New vehicles are created, updated vehicles get refreshed metadata, and sold/unavailable vehicles are set to draft. Vehicle images are downloaded and attached to the product gallery on first import.

The manual morning process was fully replaced. The site now reflects accurate inventory by 7am daily, automatically. Sold vehicles come down within hours of status change in the DMS. The team can focus on selling rather than data entry.

The business needed product inventory and pricing to stay updated from an external system without constant manual edits.

Worked on WooCommerce API integration, product data mapping, stock updates, price updates, error handling, logging, and sync workflow planning.

Improved product data accuracy, reduced manual updates, and made the store more reliable operationally.

A wholesale distributor's WooCommerce B2B store had prices and stock levels that changed constantly — sometimes multiple times per day based on supplier costs and warehouse counts. A daily sync wasn't sufficient; customers were adding out-of-stock items to cart or getting prices that had changed by the time they checked out, eroding trust with their B2B buyers.

I built a custom REST API layer in WordPress that proxies pricing and inventory requests to the ERP's internal API. On the WooCommerce storefront, I replaced the static price display and stock status with AJAX calls to these new endpoints. Prices and inventory update live in the browser before checkout. Responses are cached in transients with a 5-minute TTL to avoid hammering the ERP while still showing near-real-time data.

Customers now see accurate prices and stock levels at all times. Cart abandonment due to price surprises at checkout dropped significantly. B2B buyer trust and order completion rate improved. Order error rates fell after removing stale pricing from the checkout flow.

Failed subscription renewal payments created friction for customers and risked recurring revenue.

Improved payment recovery workflows by reviewing WooCommerce Subscriptions behavior, Stripe payment data, failed renewal orders, customer payment links, and order statuses.

Supported smoother payment recovery and helped protect subscription revenue.

A membership site using WooCommerce Subscriptions was losing 12% of its subscribers monthly due to failed renewal payments — expired cards, insufficient funds, and temporary bank blocks. WooCommerce's default behavior sent one failure email and then cancelled the subscription. Many of these were recoverable with a smarter retry strategy and customer communication flow.

I built a custom dunning plugin that intercepts WooCommerce Subscriptions' payment failure flow and replaces it with a configurable multi-step recovery workflow. Step 1: silent retry after 24 hours. Step 2: friendly card-update email + retry after 3 days. Step 3: urgency email + retry after 7 days. Step 4: suspend access (not cancel). Step 5: final notice, then cancellation after 14 days. All steps are logged and the admin can override at any step per subscriber.

Involuntary churn from payment failures dropped from 12% to under 8% in the first full quarter — a 34% improvement. The business recovered thousands in monthly recurring revenue. Subscribers appreciated the grace period and many updated payment methods in the first retry window.
