Marketplace is the team building the platform, products, and algorithms responsible for the realtime execution and online optimization of Uber's marketplace. This includes fulfillment, matching, pricing and incentives. I supported the Investments and Driver Incentives teams within Marketplace. This group of 30+ engineers powers the data driven measurement, optimization and decision making algorithms & tools for Uber’s rides & eats businesses. This involves efficiently mobilizing N-billion of Uber’s incentive spend dollars to hit aggressive growth & reliability goals. 2019 - 2020: Investments & Driver Incentives 2017 - 2019: Founded the Marketplace Experimentation team as EM + Product Lead, and grew it to 20+ folks in SF (Engineers & DS). Helped bootstrap a remote team for Uber in Toronto. 2015 - 2016: Tech Lead/Manager on Pricing - built out Upfront Pricing and led the team behind all pricing components (mobile and backend computation+serving) for the Uber Rider app rewrite
Layer was building the open communications layer for the internet. Worked on a bunch of things including server side stuff for the core messaging service, infrastructure, and features for the Android mobile SDK. Also implemented the webhooks functionality for the platform. Layer was acquired by Airbnb in 2019.
Among other things, worked as one of the key engineers on VoLTE and WiFi calling features for iOS 8. Including the handoff so that you can continue to talk when you walk in/out of WiFi coverage. Learned how to work with Carriers, large Labs/QA organizations, and spending a lot of time iterating and perfecting prototypes to something that reaches global scale.
Developed a new ultra-low latency trading engine called Speedway (https://bit.ly/33J3hL8), the system achieves revolutionary performance benchmarks and was patented by the firm Gained experience in performance oriented design, compiler optimizations, security/encryption, financial trading protocols and market connectivity.
OptumSoft is a startup building compiler technology to revolutionize the way distributed software systems are developed. It is founded by Prof. David Cheriton, commercializing his research at Stanford University. I was one of the “internal customers” of this compiler technology, developing distributed systems and deployment plans. Often followed by demos to the team and its potential clients.
Built internal iPhone apps, fixed bugs for the iPhone 3.0 OS release (it wasn’t called iOS back then) Designed and built an end-to-end prototype which could be described as a precursor to iMessage - triggering phone calls and sending SMS from your computer, using your iPhone as a server. Used things like kernel level message passing, shared memory buffers, server/client stub code generation using a scanner (lex) and a parser generator (yacc) with a bunch of networking glue.
3D surface geometry work in C++. A lot of it using OpenGL. One of three engineers on the Mac OS X port project, used Cocoa and Core frameworks to port various features seamlessly, including: the proprietary marking menus, plotting/printing and an image printing framework
Built a Customer Involvement Program (CIP) component - an application usage tracking feature - for Autodesk Maya, Sketchbook and AutoStudio. Fixed over a hundred high priority bugs in a short period in various areas of the AutoStudio code base, including: geometry/NURBS, OpenGL, image processing, plot/print, software/GL picking and object hierarchy structures
Okino provides 3D graphics rendering and data translation solutions Programmed in C++ on Windows platforms using MFC and STL; UI development with GDI+, COM and ATL Learned a lot about 3D geometry - particularly modeling and representing 3D solids.
