Software Engineer — Web Developer — Tinkerer
Status: Software Engineer at Instagram
Instagram Server Framework (2018 – present)
The Instagram Server Framework team is responsible for developer velocity on Instagram’s Python-based server codebase. I have worked on projects such as:
- The development and open-sourcing of LibCST, a concrete syntax tree and parser for Python. LibCST enables complex large-scale automated refactoring.
- A new linting framework for Python, making it easy for developers to add custom rules. We documented the work on Instagram’s Engineering blog.
- A tool for detecting networking and threading side-effects at import-time, improving the reliability of Instagram’s deployment process.
Instagram Web (2016 – 2018)
I was a Frontend Engineer managing Instagram.com. Instagram.com is a progressive web app written in React with Redux. I played a significant role in launching features and internal architecture improvements, such as:
- A redesign of the website and app.
- The Instagram Stories viewer on mobile and desktop web.
- Instagram’s modern GraphQL stack, and a migration to it.
- A migration from Flux to Redux, adding Flow types to the data model along the way.
I helped grow the team from three engineers to over a dozen by the time I left.
Facebook (Summer 2015)
As an intern on the React team at Facebook, I was responsible for porting all of Facebook’s web frontend from JSHint to ESLint, along with a large set of custom rules.
Amazon (Summer 2014)
I completed an internship with Amazon’s Fulfillment team, developing tooling for optimizing the dimensions of packaging material available to Fulfullment Center workers based on previous orders shipped from a given location. Small reductions in “air shipped” at Amazon’s scale has a great potential to reduce both costs and the footprint on the environment.
I declined a return offer in favor of Facebook.
UF ACIS Lab (Summer 2012)
Under a NSF Research Experiences for Undergraduates Fellowship grant and through UF’s University Scholars Program, I worked on IPOP and iDigBio.
Master of Science in Computer Engineering
I graduated with a 3.66 GPA from the University of Florida in December 2015 through UF’s Combined BS/MS program.
Bachelor of Science in Computer Engineering
I graduated Cum Laude with a 3.42 GPA from the University of Florida in December 2014.
An extremely easy-to-use tool for configuring and running tor relays and full bitcoind nodes. It uses a long list of technologies to automate installation, upgrades, and error recovery, as well as to provide metrics. This list includes:
- UFW (iptables)
The goal of the project is to assist these decentralized and trustless networks, by encouraging people to run them on cheap and potentially unreliable hardware or virtual machines.
A P2P VPN working by forwarding raw packets from a TAP device over UDP via STUN and TURN using libjingle (part of WebRTC) and XMPP.
- Raw packet networking with Linux Multiple routing modes (using a social graph or a fixed group)
- Cloud, mobile, and social applications
A lightweight email-focused fork of Sovereign that makes it simple and inexpensive to run your own secure email server, and migrate from an existing IMAP server.
A highly experimental AI commenting robot for the Reddit social network.
- 26 stars and 6 forks on Github.
- 6,401 comment “karma” points on Reddit.
The bot was written quickly as a prototype in MongoDB, and has since been partially re-written in CoffeeScript with MySQL.
I wrote packaging scripts for a Python-based user-friendly upload tool. Targets were:
- Windows (via cx_freeze)
- Mac OS X (via py2app)
- A Virtual Appliance (via VirtualBox and Puppet)
iDigBio is an NSF 10+ year project, so a strong emphasis was placed on maintainability. Work was done under an undergraduate research fellowship.
Pandoc is a “universal” document converter. It can output HTML, but it comes with no styling. Pan-Am is a simple responsive stylesheet written in SASS with the goal to make any document compiled with Pandoc look nice.
I personally and independently developed library to automate various web-resources operated by the University of Florida via screen-scraping.
- Medium-to-large library, containing more than 10k LOC.
- Uses LXML to parse page content.
- Designed to be fault-tolerant.
A daemon to interface between the StrongSwan IPSec daemon and GroupVPN to provide encrypted communication over GroupVPN’s Brunet P2P network. Acheron will be used to provide communication for Contrail, a cross-cloud computing framework. This project represents a collaboration between UF and VU University in Amsterdam.
GroupVPN’s functionality has since been reimplemented under the IPOP project, which provides strong DTLS encryption, obsoleting this project.
I use GPG, and we should trade keys in-person!
