WooCommerce Fix, Customization & API Integration

Mar 2025 - Present • 1 yr 8 mos

Troubleshot and customized WooCommerce stores experiencing checkout failures, payment gateway problems, cart and AJAX issues, incorrect product pricing, variation problems, shipping and tax errors, inventory synchronization issues and plugin conflicts. I worked with WooCommerce checkout flows, product variations, attributes, dynamic pricing, order processing, payment gateways, shipping rules, coupons, taxes, stock management and email notifications. I also handled conflicts involving WooCommerce plugins, themes, Elementor templates, custom PHP and WooCommerce hooks and filters. For stores requiring external connectivity, I worked with APIs, webhooks and third-party integrations involving ecommerce workflows and external systems. Customizations included checkout fields, product functionality, order workflows and other store-specific requirements. The work focused on finding the underlying cause of the WooCommerce issue, implementing a reliable fix or customization and testing the affected store functionality afterward.

WordPress Core Web Vitals & Speed Optimization

Mar 2025 - Present • 1 yr 8 mos

Optimized WordPress websites experiencing slow loading, poor Google PageSpeed scores, high LCP, CLS and FCP, weak INP, high TTFB and other Core Web Vitals problems. The work involved identifying performance bottlenecks through PageSpeed Insights and GTmetrix, then applying technical optimizations without compromising website functionality. I worked on render-blocking CSS and JavaScript, unused assets, image compression, WebP and lazy loading, browser and page caching, database overhead, excessive requests, plugin performance, Elementor and WooCommerce performance, third-party scripts and server response issues. The optimization process included performance benchmarking, bottleneck analysis, technical fixes and before and after testing across important website pages. The goal was to improve loading efficiency, responsiveness and Core Web Vitals while maintaining the existing website structure and user experience.

WordPress Malware Removal & Website Security

Sep 2024 - Present • 2 yrs 2 mos

Recovered compromised WordPress websites affected by malware, malicious redirects, injected code, SEO spam, suspicious files, backdoors and other security issues. The work involved investigating infected website files, databases and hosting environments to identify malicious activity and determine how the compromise affected the website. I handled malware cleanup, malicious script removal, suspicious file investigation, database cleanup, backdoor detection, web shell analysis, Japanese SEO spam and unwanted redirects. Where required, the work also included cPanel/server level cleanup and investigation of reinfection sources. After cleanup, I applied WordPress security hardening, reviewed vulnerable plugins and themes, strengthened security configurations and implemented protective measures to reduce the risk of reinfection. The process focused on restoring website functionality while addressing the underlying security weaknesses rather than simply removing visible malicious files.
