Marius Constantin

I build software at the edge of the continent.

Design-minded web apps, websites, and custom software. From a WordPress build to a full-stack app, with AI where it fits.

A little about me

I'm Marius. I have been programming computers professionally for about thirty years. I started in assembly and Fortran and followed the field all the way up to today's highly abstracted languages. I've worked across the full stack, through databases and web development (and now, AI), always minding both the aesthetics and the function of the software.

Away from the computer's screen there is family and laughter, there is music, there are treehouses, and there are long kayaking trips on the local rivers and the ocean.

Kind words

Marius is great to work with. He is wonderfully creative, enthusiastic, and extremely knowledgable about internet technology. In designing and producing my elegant easy-to-navigate web site Under the Table Books, he proved to be a stellar communicator and collaborator. Highly recommend!
