CUSTOM WEB APPLICATIONS

Off-the-shelf software forces your business to adapt to its limitations. Custom web applications work the other way around -- they are built to match your specific workflows, data structures, and business rules. At DMC Kreatif, we develop bespoke web applications for European businesses that need more than a website: client portals where your customers track orders and invoices, internal dashboards that aggregate data from multiple sources, SaaS platforms that become revenue-generating products, and workflow automation tools that eliminate manual processes.

Our application architecture is designed for reliability and scale. We use Supabase as our primary backend platform, providing PostgreSQL database with row-level security, real-time subscriptions for live data updates, edge functions for serverless business logic, and built-in authentication with social login providers. For applications that need more complex backend processing, we build Node.js microservices deployed as containerized workloads. Every application includes proper error boundaries, retry logic, and graceful degradation so your business operations continue even when third-party services experience outages.

Security is paramount for applications handling business data. We implement role-based access control (RBAC) so administrators, managers, and regular users see only what they should. All data is encrypted in transit and at rest. API endpoints are protected with rate limiting, input validation using Zod schemas, and CSRF protection. For applications processing personal data of European users, we ensure full GDPR compliance including data export functionality, right-to-deletion workflows, and audit logging of data access. We conduct security reviews using OWASP guidelines before every production deployment.

We build custom applications iteratively, delivering functional increments every two weeks. You get a working application early -- not a wireframe or a prototype, but actual software you can use and test with real data. Each sprint adds features based on prioritized requirements, and we adjust course based on your feedback. This approach reduces risk, surfaces issues early, and ensures the final application truly fits your business needs rather than an outdated specification document.
