Software Engineering Manager

Resume

I’m the Software Engineering Manager at iHomefinder.com where I manage a team of Software Engineers who build best-in-class IDX and CRM tools for Real Estate professionals. While I’ve been been interested in computers for almost as long as I can remember, I’ve spent the last several years honing my programming skills as a Senior Software Engineer at iHomefinder. Before that, I was the Lead Application Developer at Resera and a Systems Administrator at Ned’s Berkeley Bookstore.
