Services

Expertise in three areas

With over 20 years of experience in software engineering and cloud infrastructure, I provide three complementary services that reinforce each other.

Software Engineering

As lead engineer I design and build cloud-native systems that are scalable, maintainable and reliable. My specialisation lies in event-driven architectures and distributed systems — from platform design to concrete implementation.

Years of collaboration with DHL Supply Chain have resulted in multiple successful products on GCP: from parcel platforms and track & trace systems to driver apps and operational planning systems.

  • Event-driven architecture with Apache Kafka
  • Microservices in Kotlin, Java and TypeScript
  • Cloud-native development on GCP and Azure
  • CI/CD pipelines and DevOps workflows
  • Distributed systems and platform engineering
  • Lead engineering and technical leadership

Technical Training

As a Kubestronaut and experienced trainer, I deliver hands-on training across a wide range of modern technologies. All training material is fully self-developed — not off-the-shelf slides, but in-depth content that connects to daily practice.

Regular trainer for several large organisations and training institutes. Recognised as the go-to Kubernetes trainer for Capgemini, with dozens of sessions for engineering teams across the Netherlands.

  • Kubernetes (CKA, CKAD, CKS, KCNA/KCSA) — as Kubestronaut
  • React Development — modern frontend with hooks and TypeScript
  • Apache Spark — big data processing and streaming
  • Scala — functional programming and distributed systems
  • Angular — enterprise frontend development
  • Fully self-developed material, hands-on labs
  • Tailored for teams and individuals

Cloud & Platform Consultancy

Strategic advice and hands-on implementation for cloud platform engineering. From architecture design to full deployment of Kubernetes clusters on GCP or Azure — with security, observability and GitOps built in.

Practical experience gained in large enterprise environments such as DHL, where cloud infrastructure was directly linked to business-critical products.

  • GCP and Azure cloud architecture strategy
  • Infrastructure as Code with Terraform
  • Kubernetes platform setup with Helm
  • GitOps with FluxCD and ArgoCD
  • Observability with ELK Stack and Datadog
  • Security hardening and compliance
