Stanford Computer Science — Section Leader
Jan 2009 - Dec 2011
Intel — Web Developer & Videographer
Summer 2007 & Summer 2008
- Worked at Intel in high school, for two summers
- Built an internal video portal to improve manager-employee communication (major Intel IT initiative)
- Built web app to help engineers quickly create customer support tickets from large error report database
- Redesigned internal IT website to improve usability
- Demonstrated an attack that allows any website to have unlimited storage space on a visitor's computer.
- Works in Chrome, Firefox 3.5+, Safari 4+, IE 8+.
- Emulates user's current browser, OS, and screen size to convince them they are on trusted SSL site.
- News Feed of activity on your local network
- WireSheep lets you sniff packets on an open WiFi network. Instead of just stealing login cookies, like FireSheep, it lets you see traffic in realtime, like Wireshark. WireSheep shows you each user on the network and all the HTTP requests they're making.
- Built with teammates John Heisey, Nikil Viswanathan, and Daniel Posch.
CMSploit — Original Research
- Nearly 1% of websites built with a content management system (like WordPress or Joomla) are unknowingly exposing their database password to anyone who knows where to look.
- Temp files created by text editors may still linger after editing is finished, exposing the configuration file and database credentials to attackers.
- I wrote an automatic program to test for the prevalence of this issue across the wider web. I tested the top 200,000 websites and found that 0.77% of websites running a CMS have publicly-visible config files and database passwords.
- I discovered a vulnerability in Adobe Flash that allows any website to turn on your webcam and microphone without your knowledge or consent to spy on you.
- It uses user interface redressing (clickjacking) to trick the user into doing a series of four clicks which remotely enables their webcam.
- The exploit was covered on CNET, Wired.com, The Register, Ars Technica, Gizmodo, PC World, Yahoo! News, ZDNet, The Inquirer, and Computer World.
- We built an application for casual web designers to explore possible designs for their website.
- The designer selects a site they like and they can apply it's page layout and styles to their own site.
High School Website Team — Lead Programmer
2006 – 2008
- Built and maintained school website.

- Built club website (offline but mirrored; I'm keeping the site alive because of all the good memories I had in the club)
Sites I Built
I started designing websites at age 13
, when I first learned HTML. Since then, I've built lots of sites, mostly for myself, but a few for organizations that I like:
- Stanford student initiative to help promising youth in the Middle East and United States to learn from each other, through TED style talks, and share their ideas and experiences with the world.
Hunger and Homelessness Auction

- In 2010, we used this site to run the Stanford Charity Auction.
- In 2011, we re-purposed it to run the Stanford Hunger and Homelessness Auction.
- Items were donated by Stanford students, faculty, and local businesses, and auctioned off with all proceeds donated to the Stanford Opportunity Center.
- Youth-driven outreach organization based in my hometown.
