ABOUT ME

Joyous Rubyist, making complicated things simple.

I have a Bachelor in Business Information Systems and a Master in Communication Systems. But none of that is worth much if you're not friendly, communicative, patient and passionate - which I'm told I am.

I specialize in Rails, but I'm fullstack enough to handle a server park and to pixel-push that div there.

So let's go bug-hunting or question-answering together!

I feel home in the Ruby Ecosystem. May it be writing gems, choosing the best dependencies, or provisioning servers.

Marius is a great teacher, patient, great communicator and extremely knowledgeable. He is aware of all the best practices and pays attention to detail -- easily the top mentor I have worked with on Codementor.

Marius is an excellent practitioner, consultant and all round great person. He's been orchestrating our migration to different domains and sub-domains with different hosting plans with impressive experience and knowledge. I would not hesitate to hire Marius for a project in the future!

An upgraded Rails gem does not upgrade your Rails configuration

You need to manually specify `load_defaults` to choose which Rails defaults you want, regardless of the gem version.

Rails with Webpack - not for everyone

My personal experience from trying out Webpack in a standard Rails project is that it is not better than Sprockets. It may well be for rich-client apps, though.
