About me

As a freelance software engineer, I like to help companies with the technical design and implementation of new or existing projects. I've experience in different programming languages (Perl, PHP, Ruby, Assembly, C), and am specialized in Go (Golang) and Python.

I'm passionated about designing and developing (micro) services and API's and the implementation of protocols. I have strong skills in setting up scalable infrastructures. Currently I'm based in Amsterdam, the Netherlands, but I have lived and worked in London and Rio de Janeiro in the past.
