I help businesses stabilize, modernize, and automate legacy WordPress, Drupal, PHP, CRM, ecommerce, and payment systems. I am strongest when a project is already in production and needs careful engineering: old PHP versions, plugin conflicts, 502 errors, slow WordPress sites, WPML/multilingual setup, custom WooCommerce or Drupal features, SuiteCRM/Zoho integrations, Alipay/WeChat Pay/UnionPay flows, China hosting, and API automation. My process is practical and safe: backup/staging first, log and bottleneck diagnosis, compatibility checks, controlled rollout, rollback plan, and a clear written summary of what was fixed and what remains risky. Relevant Upwork work includes WordPress server recovery, Drupal custom development, Magento support for the Chinese market, Alibaba/Tencent Cloud setup, WeChat/Alipay/UnionPay payment integrations, SuiteCRM + WordPress projects, multilingual WordPress/WPML work, and API integrations for cross-border business workflows. If you need someone who can understand an old system, find the real cause, and fix it without breaking production, I can help.
