Custom APIs, third-party integrations, data pipelines, and system connections. REST, GraphQL, webhooks — making your systems talk to each other reliably.
Modern businesses run on connected systems. Your CRM needs to talk to your website. Your e-commerce platform needs to sync with your inventory system. Your marketing automation needs to trigger from your application events. These connections are APIs, and building them properly is the difference between systems that work and systems that break at 2am on a Sunday. We build custom RESTful APIs with documentation, GraphQL APIs for flexible data querying, third-party integration (Stripe, Twilio, SendGrid, HubSpot, Salesforce, Zapier, and 200+ services), webhook systems for real-time event processing, data synchronisation between platforms, migration scripts for moving between systems, and API monitoring and alerting. Every integration project includes rate limiting and error handling, authentication and security (OAuth 2.0, API keys, JWT), automated testing, comprehensive documentation (Swagger/OpenAPI), and logging and monitoring. Timeline: 2-6 weeks depending on complexity. From €349.70.
We define exactly what gets built — pages, features, integrations, timeline. No ambiguity. You get a written specification document before any code is written.
Database schema. API design. Component structure. Hosting architecture. We design the system before building it — because refactoring is always more expensive than planning.
Iterative development with weekly demos. You see progress every 5 business days. Each sprint delivers working features you can test on a staging URL.
Cross-browser testing (Chrome, Safari, Firefox, Edge). Device testing (12+ screen sizes). Performance testing (Lighthouse 90+). Accessibility audit. Load testing for apps.
Deployment to production. DNS configuration. SSL setup. Analytics verification. SEO validation. Then 30 days of included bug support.
