I'm a Cloud Engineer at PostNL (an AWS-centric logistics company in the Netherlands) with a decade of experience in the IT field. My expertise covers various technologies and programming languages, but currently, I'm focused on TypeScript.
As an AWS Community Builder in the Serverless category, I'm passionate about Amazon Web Services and have over 8 years of experience building solutions in the AWS cloud. I also hold 7 AWS certifications, which demonstrate my passion and expertise.
I like to experiment with different problem-solving methods and AWS solutions. Currently, I am focused on Serverless alongside DevOps.
I love sharing knowledge and own a blog where I post AWS guides: awsbythebook.com.

Next-Level Infrastructure as Code with AWS CDK and LocalStack
You know the AWS Cloud Development Kit (CDK) lets you define infrastructure as code using programming languages like TypeScript and Python, but what if you could do much more than that?
In this talk, we will see code: from CDK Constructs and Aspects to fine-grained assertions. Then, we will explore the powerful combination of CDK and LocalStack, showing how simulating AWS environments locally or in CI can help you level up your infrastructure.
When you walk out of this session, you will learn how to structure your AWS CDK projects with TypeScript, when and how to apply fine-grained assertions for regression testing and how to apply best practices with reusable CDK Constructs and enforce consistency with Aspects. Additionally, you will learn why LocalStack can be the best friend of your CDK project.
This session is targeted at Developers, DevOps Engineers, Tech Leads, or teams in general familiar with AWS and CDK basics, interested in achieving solid infrastructure patterns.
This talk falls into the 300-400 level, and I expect you to be familiar with AWS and infrastructure as code tools, as well basic understanding of CDK.
The duration is 30 minutes of focused content, or 45 minutes with Q&A.
