WordPress Development & Integration
Custom extensions, API integrations, and seamless embedding into your system landscape.
Standard software often covers 90% – we close the last gap. We develop Plugins & Headless, connect WordPress with your tools, and automate workflows.
Our Development Services
From API integration to complete custom solutions – we cover the entire spectrum.
API & Interface Integration
We make your systems talk to each other. Whether REST, GraphQL, or webhooks – we connect software with your CRM, ERP, or identity provider.
- Bidirectional data synchronization
- Third-party system connections
- Custom webhooks & event handlers
- Legacy system integrations
Custom Middleware & Logic
Often data formats from System A don't match System B. We develop middleware that sits in between, transforms data, and controls processes.
- Transformation layer (ETL)
- Data stream validation
- Caching layer for performance
- Microservices architecture
Embeddings & Custom Apps
Want to use software features in your own intranet or customer portal? We embed software headlessly and build custom UIs around it.
- White-label integration
- Custom dashboards (React/Vue)
- UI extension via plugins
- Mobile app customizations
Automation & Bots
Save manual work through intelligent automation. We develop bots and scripts that handle tasks automatically.
- ChatOps & slash commands
- Automated reporting
- Workflow orchestration
- Trigger-based actions
Beyond Blogging: Enterprise Framework
We don't use WordPress as a page builder, but as an application framework. With headless architecture and custom endpoints, we build scalable portals.
REST API & Headless
Decoupling frontend and backend. We use WP as a content engine and deliver data via REST/GraphQL to modern frontends (Next.js, Astro).
Hooks & Filters
Deep customization of core logic via the hook system. We modify query logic, authentication, or email workflows without patching the core.
Custom Blocks (React)
Development of custom Gutenberg blocks with React. Editors receive tailored input forms that strictly follow your corporate design.
Concrete Use Cases
How we implement WordPress development in practice.
Headless Corporate Portal
WordPress frontend is too slow and insecure.
WordPress only as headless CMS behind a firewall. The frontend is a statically generated Next.js app on edge network.
Product Sync with ERP
WooCommerce products must be maintained manually.
Middleware that syncs 50,000+ items nightly from ERP (SAP/Navision) via WP-CLI and REST API.
Development with Foresight
Update-safe, scalable, and secure – why you should trust us with your development.
Update-safe (No Core Hacking)
We don't modify the open-source software's source code. Instead, we use official APIs and plugin architectures. Your installation remains updatable and maintainable.
Full-Stack Expertise
We understand not just the code, but the infrastructure beneath it. Our developers know how queries affect database performance and how to build scalable APIs.
Modern Tech Stack
We use modern, type-safe technologies: React, TypeScript, Node.js, Python, Go. Plus PostgreSQL, Redis, and Docker/Kubernetes for infrastructure.
Security by Design
Every line of code is written with security in mind. Input sanitization, secure authentication (OAuth2/OIDC), and compliance with data protection regulations are standard.
Our Tech Stack
How We Work
From requirements to go-live – transparent and structured.
Analysis
We review API documentation, analyze your requirements, and identify optimal integration points.
Architecture
We design the solution: middleware, plugin, or script. Data flows, interfaces, and security concept are defined.
Development
Agile implementation with code reviews, automated tests, and continuous coordination. You see progress in real-time.
Deployment
Integration into your CI/CD pipeline or hosting on our infrastructure. Documentation and training included.
