All 24 department FAQsWhich CMS platforms do you write custom plugins for, and why choose a bespoke module over marketplace add-ons?
We develop custom plugins and extensions for WordPress, WooCommerce, Joomla (4/5/6), and OpenCart (3/4) packaged as clean, update-safe installable archives. Unlike bloated multipurpose add-ons, a bespoke plugin executes your exact business logic with zero performance drag — see our custom CMS plugin engineering guide.
Do you take over, accelerate, and modernize existing websites and stores built by previous agencies?
Yes — rescuing and evolving existing platforms is a core specialty. Through our custom website development & CMS modernization service, we audit legacy WordPress, Joomla, OpenCart, and custom PHP codebases on staging, perform zero-downtime upgrades, eliminate speed bottlenecks, and preserve 100% of your SEO equity. Read how we achieve 95+ Google Lighthouse scores.
Which e-commerce platforms do you build on, and do you integrate ERP systems, wholesale pricing, and payment gateways?
We engineer high-converting B2C online stores and B2B wholesale platforms on WooCommerce, OpenCart (3 & 4), Joomla, and custom PHP stacks — complete with two-way ERP synchronization, tiered B2B customer pricing, automated XML/API supplier feeds, Stripe/instant payments, and multi-carrier logistics.
How do you protect existing Google rankings when redesigning a website or migrating an e-commerce store?
Before launch we compile a complete 1:1 301 redirect matrix, preserve canonical slugs, metadata, headings, hreflang pairs, and Schema.org structured data, validate /sitemap.xml, and monitor post-launch indexing directly via the Google Search Console API.
