• Designed and implemented highly efficient DbScan algorithm using OpenCL and CUDA. For

our inputs, my algorithm ran in 0.2ms, 200x faster than alternative open source solutions.

• Designed, implemented, and retrofitted a Scala exception-safe resource management framework

meant to primarily deal with resource leaks.

• Implemented low-allocation, fast Scala libraries (matrix ops, profiling, ...)

• Implemented a framework for auto-generating CAN message parsers and handlers.

• Second engineer on a team that build App Campaign for engagement (ACe) which servers

billions of ads daily and generates more than $1.5 billion in yearly revenue.

• Collaborated with 10+ teams to deploy and improve the performance of engagement ads on 4

different serving stacks.

• Took ownership of and rewrote a pipeline that computed user lists (audiences) used primarily by

engagement ads. Dramatically increased the accuracy of the user lists and decreased advertiser

tickets.

• Migrated engagement ads for the AdMob network from one serving stack to another, after two

previous teams attempted but failed to achieve performance parity on the new stack.

• Designed and implemented a novel framework for building exploratory bid landscapes that were

more precise than the log-based bid landscapes in use.

• Designed and implemented a unified tool for investigating problems with re-engagement ads.

Impact: 50% decrease in time spent by gTech on tickets as well as reduced escalations to

engineering.

• Revived IOS re-engagement ads after IOS14 privacy policies made serving impossible.

• Wrote a tool that facilitated quick deployment of emergency patches.

• Wrote a tool that made debugging remote instances easier.

• Wrote a tool that facilitated quick deployment of emergency patches.

• Wrote a tool that made debugging remote instances easier.

I worked on the imo.im website which was a chat aggregator

that turned into a social network.

• Designed and implemented audio and video calls using Flash (ActionScript).

• Co-designed, implemented, and deployed a framework that allowed developers to write multi-

user serverless apps (i.e. small games) that used imo.im for communication.
