Kevin K.

Senior WooCommerce/PHP engineer with more than 25 years of experience solving custom code failures, checkout and payment problems, integration issues, performance bottlenecks, security incidents, and infrastructure problems for established businesses. My work includes backend integrations with legacy systems, hands-on Linux server administration, and priority incident response when technical failures put revenue or customer relationships at risk. If your store is already generating revenue and something is broken, slow, unreliable, poorly integrated, or disrupting checkout and payments, you probably do not need another plugin installer. You need an experienced problem solver who can diagnose the root cause, work across the full stack, resolve the issue correctly, and provide clear professional reporting on what was found, what was changed, and how those changes resolved the problem. I am especially useful for established ecommerce businesses dealing with: • Custom WooCommerce checkout functions, fields, cart logic, order flow, subscriptions, shipping, tax, and payment failures • API and backend integrations with CRMs, ERPs, fulfillment systems, inventory platforms, payment gateways, shipping providers, and legacy business systems • Custom PHP development, MySQL troubleshooting, plugin development, WordPress hooks and filters, backend logic, and theme or plugin conflicts • Performance problems caused by plugin overload, inefficient database queries, caching failures, LiteSpeed configuration, or unstable hosting environments • UX/UI problems, broken forms, mobile display issues, confusing navigation, inconsistent layouts, and checkout friction affecting customer experience or conversions • Fake registrations, spam orders, card-testing attacks, checkout abuse, malware, fraud controls, and WordPress security hardening • WordPress critical errors, database failures, white screens, failed migrations, broken layouts, and site restoration • Linux, cPanel/WHM, DNS, SSL, email, and server problems affecting store performance, reliability, or deliverability Effective troubleshooting requires more than reviewing plugins or reading error logs. I test the website as an actual customer would, following the same navigation, registration, account, cart, checkout, payment, and post-purchase processes. This allows me to reproduce the problem accurately, identify where the customer experience breaks down, and trace the visible symptom to its technical cause. For larger WooCommerce projects, I can also serve as the technical lead, coordinating developers, designers, hosting providers, DNS and email vendors, payment processors, API partners, and business owners so the work is completed correctly across every system involved. I am not the best fit for bargain theme installations or basic brochure websites. My experience is most valuable when WooCommerce is mission-critical, revenue is being affected, and the business needs senior technical judgment without having to supervise a junior developer. Past clients have described me as: “Extraordinarily well-rounded… he can wear many hats technically.” “Super knowledgeable and helped empower us with that knowledge.” I work quickly, communicate directly, and take pride in solving difficult ecommerce problems. My objective is not merely to make an error disappear, but to identify the root cause, implement a reliable solution, and clearly document the work performed.
