Engineering Protocols & Capability Matrix
Our uncompromising standards for delivering production-ready, sub-second web platforms.
Primary Platform Architectures
We specialize heavily in enterprise WordPress while delivering high-converting Shopify stores and ultra-light Ghost publishing setups.
WordPress Architecture & Custom Themes
We transform WordPress from slow page-builders into blazing-fast enterprise platforms. We engineer bespoke object-oriented PHP themes, tailored Gutenberg blocks, custom post types, and headless REST/GraphQL architectures that load in milliseconds.
Shopify Liquid 2.0 Storefronts
Custom Online Store 2.0 theme builds, Liquid architecture, bespoke cart drawer extensions, and conversion-optimized purchase funnels engineered for high-volume retail.
Ghost CMS & Memberships
Ultra-clean Handlebars themes, Stripe member integration, sub-second edge rendering, and instant newsletter delivery for high-velocity digital publications.
Engineered for Measurable Results
What our enterprise partners and founders say about working with the Slenio team.
"Slenio completely rewrote our legacy WordPress site into custom Gutenberg blocks. Our load time dropped from 4.8 seconds to 0.4s and our organic search conversions skyrocketed by 340%."
"Their Shopify Liquid mastery is unmatched. They engineered a custom product customizer that handled our Black Friday traffic without a single hiccup. Slenio is our go-to engineering partner."
"Whenever we have a critical bug or need a custom API integration, Slenio resolves it in hours. Their ongoing maintenance plan provides total peace of mind for our multi-brand network."
Architectural Inquiries
Standard page builders (Elementor, Divi) inject massive CSS/JS bundles for simple layouts, destroying TTFB and Core Web Vitals. Slenio builds bespoke Gutenberg ACF blocks that render semantic HTML with zero overhead, scoring 95+ on Google PageSpeed while giving your editors an intuitive drag-and-drop experience.
Yes. While WordPress is our primary core flagship, we build custom Shopify Liquid 2.0 themes, checkout extension apps, and high-velocity Ghost CMS publications with Handlebars and Stripe paywalls.
Our maintenance plans include 24/7 uptime monitoring, weekly updates tested in isolated staging environments, automated daily cloud backups, security patching, and emergency rapid-response developer hours under 60 minutes.
Absolutely. We build custom plugins and middleware connecting your website with HubSpot, Salesforce, Stripe, PayPal, Mailchimp, ERP systems, and proprietary REST/GraphQL endpoints.
