I’m a DevSecOps/Platform Engineer and full-stack developer with a strong background in middleware technologies, API management, and secure platform delivery. My experience spans OSB (Oracle Service Bus), SOA (Service-Oriented Architecture) implementations, API Gateways (Kong), and modern cloud-native stacks. I bring deep technical skills combined with a practical, business-oriented mindset, ensuring solutions are secure, maintainable, and aligned with operational needs.

What I do well
  • Middleware & Integration: Over a decade of experience with OSB, SOA Suite, and middleware patterns—designing, deploying, and optimizing integration flows for enterprise environments. Skilled in transforming and orchestrating services, applying governance, and ensuring high availability.
  • API Management & Gateways: Extensive work with Kong API Gateway for routing, plugin management, API spec lifecycle automation, and performance monitoring. Capable of integrating gateways into CI/CD pipelines for reproducible and auditable deployments.
  • Platform & Developer Experience: I build internal developer platforms in Backstage, including custom plugins for Kong and Kafka. These dynamically register APIs/specs from multiple environments, run periodic syncs, and integrate with GitLab for traceable changes.
  • Identity & Security: Secure SSO and OIDC flows with Keycloak and Azure AD, hardened Docker deployments, SSL/TLS configuration, and role-based access control aligned with least-privilege principles.
  • Product Engineering: Full-stack web and mobile apps using React/Next.js, Flutter, Firebase, and Supabase. Integrations with Stripe for billing, Brevo for email, Twilio/WhatsApp for messaging—designed to allow multi-tenant or bring-your-own-service setups.

    Fluent in Dutch, English, I excel at bridging business and technology—delivering solutions that are not only technically sound but also operationally effective.
