Description

As a seasoned Cloud & DevOps Consultant with over 7 years of experience, I help businesses translate complex needs into scalable, resilient, and secure cloud-native solutions. Based in the Netherlands, I specialize in designing and implementing robust AWS infrastructure using Infrastructure as Code (Terraform/CDK) and optimizing systems for performance and cost-efficiency.

My core expertise lies in:

Cloud Architecture: Designing secure and scalable AWS architectures (including serverless and IoT platforms) tailored to your specific business and compliance requirements.
Infrastructure as Code (IaC) & CI/CD: Automating infrastructure provisioning and deployment with Terraform, CDK, and GitHub Actions to accelerate delivery and ensure consistency.
API Development & Modernization: Building high-performance REST APIs (Go, Lambda) and rescuing delayed modernization projects to restore on-time delivery.
Security & Performance: Conducting vulnerability assessments (ZAP) and performance testing (up to 1,200 rps) to deliver production-grade, reliable systems.

With a background in consulting at Deloitte, I excel not only in the technical implementation but also in project management (PMO), workflow analysis, and aligning multi-vendor roadmaps to mitigate risks and reduce costs (e.g., cut cost overrun risk by 20%).

I am passionate about building sustainable systems that deliver real-world impact. Let's connect to discuss how I can help you achieve your project goals.
