I am the tech lead for Instagram Direct Messaging infrastructure and was also the lead architect and engineer for cross-app communication between IG Direct messaging and Facebook messenger.

acquired by Gusto in 2021

I was a co-founder and the CTO of Ardius. I architected all and implemented most of the backend systems for the first version of the R&D credit tool which was used in production successfully for many clients. I also co-architected and implemented a lot of the frontend (reactJS).

Some public things that I made during this time for Ardius:

1. Discretion

   A privacy/authorization framework for Ruby on Rails applications

2. GRR

   A template for a fully-functional Ruby/Rails/ReactJS/GraphQL application

3. omniauth-quickbooks-oauth2

   An omniauth strategy allowing authentication via Intuit’s OAuth2 flow

4. apollo_fetch_upload_rails_middleware

   A fast and efficient server implementation of multipart file uploading via GraphQL mutations using the Apollo React framework against a Rails application (before you had to base64 encode file contents which of course is inefficient)

I worked on a lot of products and teams at Facebook and as a tech lead a few times. Some highlights:

1. Site Integrity

   I helped build the infrastructure for fighting spam all across the site. The infra I built fought fake accounts, phishing, malware, commercial spam, and many other forms of attacks.

2. Notifications

   I was the tech lead on a team that built the experimental Facebook Here product

3. K-12 Education Initiative

   I was a senior engineer on the Facebook partnership with Summit Public Schools. We built software for teachers and students which was used to create and facilitate a personalized learning experience in schools

I worked on the Social Plugins team where I helped improve several social plugins including the Like Button and Comments Plugin.

I also built the Send Button

At the end of my internship, I was offered a full-time position.

I planned and taught sections, graded papers, and held office hours for CS105: Introduction to Computer Science for Non-Majors.

I did general web coding and also designed and built a new, non-Flash video player interface for SCPD which students used to watch recorded Stanford course lectures.

I designed and built a search engine mining framework which generated statistics around internet keyword searches. This data was then used to augment the company’s core algorithms.
