I have written web crawlers which scraped certain information from a page in Ruby before, making this project a good fit for me. I've got extensive experience in Ruby and web development (five years professionally), and am a Junior studying Computer Engineering at UC San Diego, giving me a solid computer science background.
I believe I will be able to complete your project in three business days, and will work closely with you to remove any latent bugs that I do not catch during my debugging process.
All in all, your project sounds very interesting! I looking forward to hearing back from you.
