Lead iOS Developer

(9 months)La Jolla, CA

Lead iOS Developer

(3 months)Greater San Diego Area

CourtSocial is a social media mobile app for sharing photos and quick polls (similar to Blurtopia). As the lead iOS developer I worked to implement both the iPhone app and Django-based RESTful API.

CEO & Co-Founder

Breadcrumbs, Inc.
(1 year 1 month)Greater San Diego Area

Breadcrumbs is a mobile app startup (Android and iOS), which I founded at San DIego Startup Weekend 2012 with a small team. I successfully pitched to the EvoNexus startup incubator and was one of the 6 of 110 companies admitted, and also got a $50k seed investment from Qualcomm Labs. I developed the iPhone Breadcrumbs app and created the Django-based server admin, which aggregated data from Facebook and Foursquare for display in the iPhone app.


Joel's Transcription
(6 years 10 months)

Small audio transcription service offering audio transcription by highly educated college students from UCSD. I do some of the work myself and contract some to fellow students at UCSD.

Human Factors Engineer

(6 months)Rancho Bernardo

At Sony I conducted in person usability tests for Windows 8 running on Sony tablet and desktop computers. The most interesting part of my job was doing contextual interviews - observing and speaking with users as they interacted with user interfaces

Brand Services Engineer

(1 year 10 months)Greater San Diego Area

This was a half technical / half design job where I was tasked with designing (information architecture, usability analysis) and developing (using custom GUI application and some SQL) menus for EMN8’s touchscreen kiosks, which customers could use to order fast food.



A fun mobile app for exploring Twitter.
