  • Received early promotion to Senior Software Engineer within first year of joining.
  • Optimized data path from the self-driving car to the phone to achieve sub-300ms latency in support of streaming real-time telemetries to the safety driver.
  • Co-authored this patent based on my work designing and building the tool suite that enabled roadside assistance team to navigate to a self-driving car on public roads within minutes of an incident.

Google

Software Engineer
Aug 2016 - Feb 2019

gRPC is Google's next-gen RPC system, built from the ground up in open source. gRPC is a highly performant system built around a simple yet powerful wire protocol. The library provides idiomatic APIs in nine supported languages. Through 250+ pull requests, and even more internal changes, I have contributed mainly to gRPC's C core. I have also made significant contributions to the C++ and Python wrapped layers. Some highlights include:

  • Created the team's internal benchmarking framework, automatic regression detection system, and performance dashboards.
  • Migrated TensorFlow's distributed runtime to use gRPC internally at Google.
  • Implemented connection-level monitoring feature for the C++ stack, which exports critical debugging data of live services and presents them in a simple HTML page.
  • Co-authored RFC for gRPC client retries in 2017. It is now implemented across all language stacks.
  • Created and delivered 40 minute tech talk on gRPC performance at KubeCon.

Read on 2025/07/03


Missed this classic in High School (shame on you Shaker!). It was absolutely nothing like I expected it would be based off pop culture. I was waiting for mobs, Fritz/Igor, and "it's alive" before realizing all that stuff was added by later movie adaptations.

Instead I got stories with in stories told in beautiful language and varying structure on themes of ambition, science, love, etc etc etc. Anyway, it was great.

Shoutout to Guillermo del Toro for the catalyst to read.
