## Work Experience
### Software Engineer @ Ghost Autonomy
Jan 2021 – Present | Mountain View, California, United States
• 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.

### Senior Software Engineer (App Campaign for engagement) @ Google
Jan 2016 – Jan 2021 | Mountain View, California, United States
• 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.

### Software Engineer @ Palantir Technologies

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

### Software Engineer @ Moka5

Moka5 built a virtualization platform that allowed corporations/admins
to easily manage user desktops.

independently installed applications in order to create custom images for users.
