JJ turns out reliable, high performance software…He's hard working and honest, and he writes some of the cleanest code I've had the pleasure of reading — Patrick Tufts, co-founder of 24 Hr. Diner

Status - I just joined a new startup.

Education - I have a Bachelor of Arts (with honors) in mathematics with a concentration in computer science from St. Mary's College of California. I won the Br. Alfred Brousseau award for "outstanding scholarship as a mathematics major."

Profile - I am an enthusiastic and friendly extrovert. My most notable traits as a programmer include: an incredible dedication to producing clean, well-documented code on time and on budget; a passionate love of programming and especially programming languages; and a commitment to the open source community.

Career Objective - I would like to program in an innovative, results-oriented company where I am required to consistently solve difficult technical problems. Clean code, a clear direction, and a healthy life balance are the things I look for most in a company.
