Projects

Things I've built that I'm proud of

Funzo

Funzo is a fully featured library to use union types in C#. By default, it has the Result and Option types and source generators in order to have dedicated types for your business concepts.

C#

Sorse

Sorse is a little helper created just to use in Funzo. It allows you to define Source generated content with a fluent interface so you don't have to concatenate strings manually

C#

Join PDF utility

Small and dirty utility created to join PDFs locally, without uploading documents to the internet.
