About Me

My name is Pieter Joost van de Sande and I am an independent software architect with an impressive track record with a focus on message based systems. I also share my experience on stage at international conferences like Microsoft TechDays, SDC and NDC.

In my spare time, I contribute to open source projects which, as you can see at my Github profile, are not bound to a specific programming language or platform. I rather explore different languages and paradigms to learn from their differences. I see C# as a great general purpose language, the JVM has an impressive ecosystem and Go shows how eligant simplicity is. I do prefer static typed languages in most situations, but if you really want to learn TDD, dynamic languages are your friend.

My role in the community is recognised by Microsoft and awarded me with the exclusive Microsoft MVP award.


The following technologies are the ones I've recent experience with:

Google Go, .NET Core, C#, Java, Kubernetes, Docker, Akka.NET, Apache Kafka, Microservices, FoundationDB, SQL, Domain Driven Design, Javascript, TDD, React, VSTS, Git, OpenID Connect, CI/CD, Azure and Optimization algoritms.

2007 - 2018
Contributed to the The Dark Side of Event Sourcing
 Vrije Universiteit Amsterdam, Utrecht University

Evoling software systems includes data schema changes. These changes are not trivial for running systems that always need to be continious available. Event Sourcing can add an extra layer of complexity to this. I've participated to the studio that lead to the The Dark Side of Event Sourcing paper as an expert with experience in Event Sourcing.

Finished 155 days Github Streak

I love a challenge because it offers me an opportunity to grow. In 2015 I challenged myself to do a Github Streak of 30 days. This means, making at least one contribution at a public repository at Github every single day straigth. After 30 days I couldn't stop, so I continued for 155 days straight days and made 2,091 contributions in total that year.

The people we look for to work on Next are extremely hard to find. We are very happy that Pieter Joost possesses that quality and is helping us to realize our dream.

- Bas van der Veldt, CEO at Afas

Pieter Joost is one of the rare breed that understands what it takes to build a system of systems in a way that is sustainable long term. Seeking speed and fast feedback I've seen him reduce friction at many levels of the development spectrum. Whether it is simplifying thinking about system interactions, remodelling the core domain for understandability or automating an otherwise human procedure, he will put a smile on your face.

- Rob van der Linden Vooren, Software Architect at DoubleDutch

Pieter Joost has proven to have great knowledge of building software and was capable of learning quickly in a branche he wasn't familiar with. He was easy to work with and always prepared to take that extra step. He was worth every euro I spend on him.

- Robert Heinen, CEO Van Brug Software

Working with Pieter Joost is an enervating experience. His enthusiasm for software development in it’s broadest sense and his (literally) endless energy work very contagious. This combined with his broad knowledge of software technologies, development processes and his visions on the usage of ICT made him a very useful addition to our team.

- Arno den Uijl, Architect at ABN AMRO


I am available for short- and long-term contract and consultancy work, so go on... hire me!

Usually I charge by the hour, but sometimes (e.g. for training or architectural review) I can also give you a fixed price offer. My prices are fair, but expect to pay more than you would normally pay for a development consultant, but less than a licensed lawyer, accountant, management consultant, or similar.
