What We Build

Comprehensive WordPress Engineering

01

Custom Gutenberg Theme Development

Coding custom block themes from scratch, utilizing React and native block layouts for an intuitive editor experience and fast load speeds.

02

Private Plugin Engineering

Developing custom plugins to handle specific backend operations, CRM integrations, or custom post types, avoiding unoptimized third-party additions.

03

Headless WordPress (Decoupled CMS)

Decoupling the WordPress backend (using the REST or GraphQL API) from a modern frontend like Next.js, yielding fast performance and security.

04

Core Web Vitals Optimization

Compressing asset payloads, implementing lazy loading, deferring non-critical JS scripts, and setting up caching to achieve Lighthouse scores above 90.

05

Enterprise CRM & API Integrations

Connecting WordPress with external CRMs (Salesforce, HubSpot), analytics tools, and internal database systems via secure API adapters.

06

Security & Vulnerability Patching

Setting up secure login rules (MFA/SSO), implementing secure web firewalls (WAF), and auditing code to prevent SQL injection and XSS exploits.

The Challenge

WordPress powers 40% of the web. But most sites are slow, bloated, and vulnerable.

WordPress is a powerful content management system, but poor implementation ruins its utility. Stacking heavy pre-made themes and dozens of unoptimized plugins creates slow loading times, layout shifts, and major security vulnerabilities. Slow web pages drive visitors away and lower search engine rankings. Quecko builds WordPress websites differently. We write clean, custom PHP and React codebases, build lightweight page components using native Gutenberg blocks, write private plugins to handle custom functionality, and implement security protocols to protect your site.

FAQ

Frequently Asked Questions

Page builders like Elementor add excessive CSS and JS scripts to your pages, which slows down load times. Native Gutenberg blocks use WordPress's default rendering engine, yielding faster load speeds and a cleaner editor experience.

In a headless setup, WordPress functions as the content database (CMS), while a modern JavaScript framework (like Next.js) renders the frontend layout. This approach offers fast load speeds, design flexibility, and improved security.

We use clean custom code, restrict administrative login access, enforce MFA, use secure web application firewalls (WAF), and keep all dependencies updated to protect against SQL injections and cross-site scripting (XSS).

Yes. We can write custom plugins to interface with external REST/GraphQL APIs to sync content, capture leads, or feed user data directly to your internal database systems.
