Engineering manager

September 2023 – Today

Today, I am an engineering manager leading a small team dedicated to develop software for personalisation and recommender systems. This role affords me the privilege of seamlessly blending managerial responsibilities with hands-on software development.

Senior software engineer

August 2021 – August 2022

While serving as a software architect, I missed the hands-on joy of development. In my next project, I immersed myself in greenfield software development within a fully serverless cloud environment. The AWS lambda functions are written in TypeScript and connecting with AWS IoT Core via MQTT. High performance communicating and low latency is key, so this made it an interesting challenge!

Software architect

July 2020 – August 2021

Moving on from technical lead of a single team, I have been promoted to be software architect overarching multiple development teams. I fully focussed on creating high level solution diagrams, participation in technology selection and advocating technical guidelines and principles. I provided reviews to implementations of multiple teams and guide them with high quality standards. Together with other architects, we try to find the right balance between technology and the product requirements of business stakeholders during the creation of roadmaps and assigning priorities.

Technical lead

October 2017 – July 2020

I gradually have been promoted to lead developer, until I had the chance to prove myself as a technical lead for the creation of a greenfield event-driven gaming platform. This microservices platform contains a mix of technologies and focuses on the right tool for the job. Symfony is chosen together with Node. RabbitMQ is used as central communication tool between the services where MongoDB and Redis are the preferred databases. As a huge fan for domain-driven design, each service is strictly following this approach with command-query-responsibility-segregation finishing this buzzwords list.

Eeek, my tests are mutating!

SymfonyCon Amsterdam 2019SymfonyCon Cluj 2017PHP Ghent

Writing tests is nice, but how are you sure that your tests cover all use cases? Code coverage can give false positive metrics. A new way of working that goes by the name of mutation testing has gained a lot of popularity lately. This talk will explain you what it is, how you can integrate it and contains a demo over the basics of mutation testing with infection and phpspec.

Introduction tactical Domain-Driven Design

Private consulting

You may have heard of Domain-Driven Design. That DDD makes for more understandable and readable code. You may have even heard that DDD focuses on communication, modeling and business processes.
Starting with DDD sounds big and scary, doesn't it? This presentation explains the basic terms and how you can apply them tomorrow.
