Hello — my name is Raymond. I'm a fourth-year undergraduate at Princeton. I last took a gap year in California to work at startups including AngelList and Terminal.

Before that, I built data tools at Addepar and Facebook, was a partner at the Dorm Room Fund, and helped start the HackPrinceton hackathon. Before that, I built robots and hardware and led a FIRST Robotics team.

I work at the intersection of engineering and design, and am especially interested in products that create new social and intellectual practices in the areas of 1) knowledge 2) information networks 3) media and communication.

Work & Internships

Worked on design and frontend engineering, focusing on the in-container development environment that is the main user interface to Terminal containers.
Worked on new features and improvements in the fundraising, talent, and platform areas. Built an quality signal for AngelList Talent candidates called "one of the best features in the product".
Investor in amazing student-run startups, involved at all stages from deal sourcing and diligence, to closing investments and portfolio support.
Worked on a rewrite of the core visualization library for Addepar's financial analytics platform, which was later open sourced as Ember Charts.
Built several data tools for internal teams.
Built the Wordpress/PHP frontend used at 500 Startups demo day.

Engineering Portfolio

Ember Charts
Open source components from my internship at Addepar.

I spent most of summer 2013 rewriting and extending the visualizations in Addepar's financial analysis platform.

I worked with our UI Engineering team lead to review previous charts work and come up with a performant and extensible architecture (using computed properties to create data pipelines for each chart's intermediate calculations).

Work included implementing a half dozen responsive visualizations in Ember.js and D3.js, including support for color, animations, and interactivity, with much help from Addepar's information designer.

We then worked with Ember.js creators Yehuda Katz and Tom Dale on a small open source release, which now has 400+ stars on Github.

Anonymous social network. 3-6k MAUs, 30-60k pageviews/mo.

PFML is a moderated anonymous social site at Princeton. Think of it as Whisper or Secret, before either of those existed.

I worked with two nontechnical partners, building most of the site in Wordpress and PHP over the course of a day. It was a clone of the now defunct CollegeFML network, and competed with another FML clone created by a friend for several months.

Today, PFML gets several tens of thousands of pageviews a month, particularly around midterms and finals period.

Design Portfolio

3 clicks to start receiving file uploads directly in your Dropbox.

Filer is a Dropbox API app that simplifies the process of receiving files from people, by generating short links that they can use to directly upload files to your Dropbox.

Links expire after a set amount of time; log in with your Dropbox account again to get a new one.

Make sure you have Dropbox notifications enabled, so you'll know immediately when a file gets uploaded.

Filer was a solo project at HackPrinceton, where it won 2nd place and a $1000 prize.

Candidate Quality Signal
A quality indicator for candidates on AngelList Talent.

AngelList Talent lets companies and job seekers indicate interest in each other, and introduces them when there is a match.

As a side project I reworked what happens when a candidate indicates interest in a startup, to tell the startup how many startups the candidate was interested in.

This allowed startups to tell apart candidates specifically interested in them, from those conducting a broader search, from those saying yes to hundreds of startups.
