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.

Building Scalable CI/CD Pipelines with Self-Hosted GitHub Actions on AWS CodeBuild
Discover how PostNL is transitioning to a serverless CI/CD solution by hosting GitHub Actions on AWS CodeBuild. This session dives into the architecture and practices that centralized workflows in a single AWS account while maintaining scalability and security.
Attendees will gain practical insights into setup, cost optimization, and best practices for managing workflows in a large AWS organization environment.
Refactoring a Lambda Monolith to Microservices Using Hexagonal Architecture
In many applications, a single Lambda function contains all the application logic that handles all external events. The Lambda function sometimes acts as an orchestrator, handling different business workflows within complex logic. This approach has several drawbacks, like big package size, difficulty enforcing least privilege principles, and hard to test.
In this session, I will explain how to leverage the Hexagonal Architecture, also known as the “Ports and Adapters” approach, to refactor a Lambda monolith into microservices.
