Adding GitHub to resume?

[Phil]

Hey Quantnet,

Just asking for some quick resume advice tips. Top US school and two year hedge fund quantitative developer.

There's this new role that popped up. I'm interested in applying. The job requires "superior software skills" and "sound knowledge of option pricing."

Besides my quant research related iPhone app released in the AppStore and my Futures magazine publication, I'm thinking of adding to my resume points which showcases the above two requirements. Of course, what I include is honest work I've been doing on my own for the past view months. What do you think of:

1. A link to my GitHub account where you can download compilable source code of a pricing engine, maybe backtester, I did in C#?
2. Independent but unpublished research pertaining to the work involved in this job. It's on arXiv.

Basically, would 1. and 2. be seen as a genuine attempt of convincing HR I'm a strong candidate for the role. Or would HR just call BS immediately. It IS code and research I've did.

Also, do investment banks ever read cover letters, even if it's a very short one?

Thanks,
Phil
