A lead architect and developer with over 15 years' experience, I love to make software you can absolutely rely on.

I strive for as simple as possible, yet no simpler, to ensure your project is easy to maintain, easy to adapt and easy to work with. I did this for Travelex, designing and coding the automated, cash processing operations software (Taxidia) in their London cash center. I pushed hard to first develop a minimal viable version and only start adding features based on real-world user feedback. My leadership resulted in vastly different features than originally planned, and in vast savings of time and money otherwise wasted on unnecessary features. It ended up with half a million lines of C#. I coded over 25% of it – I enjoy doing what it takes to get the job done.

My clients get more than an expert in C# / .NET, Haskell and SQL. (I also have experience in Erlang, F#, JavaScript, Python, Ruby and Rust, and database-wise: PostgreSQL, MySQL, Microsoft SQL Server and several NoSQL databases.) They get a polyglot who assimilates new languages rapidly and has a solid background in system and network engineering. I can handle nearly any programming task you throw at me.

You can rely on my software, and you can rely on me.

Work Experience

CEO, Lead Architect and Developer SRU-Systems B.V. Sep 2015 - Present

With software taking over the world, we realize it's essential that it becomes much more reliable than it is today. We achieve this superior reliability by designing and building software that is as simple as possible but no simpler. Our strategies include striving to prevent unnecessary features, replace error-prone techniques with safer ones, and use strongly-typed languages when possible. Simply put, we make software that both our customers and their customers can absolutely depend on.
