Eric Tjossem

Frontend developer with a passion for beautiful design (641) 990-9591

Hi, I’m Eric! I build applications that help people overcome problems.

My recent work in Angular.js - paired with a Python-based API - has given me an incredible appreciation for the power of a single-page app framework, though I’ve got a soft spot for cleanly organized Ruby on Rails apps. I strongly prefer working with small, highly collaborative teams in a development culture that values the user experience above all else.

A web application can’t survive on code alone; even as a developer, I often find myself building my own mockups for projects and considering interactions carefully from the perspective of the customer.

If you’re interested in working with me, or just want to talk about your project, email me at or tweet @etjossem.
