Elixir Deployments and CPU Usage
Background
For the past semester, I have deployed a custom shortlinker service and my personal website on a Google Cloud Compute Free Instance. The custom shortlinker is a rewrite of the CS61A Shortlinker in Elixir, which was a good way for me to learn the new language. Upon deploying the Elixir version, however, I noticed that CPU usage hovered around a constant 100%, even the system was idling. I left it alone for a while, noting that it was responding to requests fairly quickly, leaving me to think that it was likely the BEAM that was idling.

EE375: A Coffee Chat
Introduction
Hello! This is a talk I gave at EE375, an introduction to teaching techniques class required at UC Berkeley for first-time TAs. The content is largely based on James Hoffman’s techniques, with inspiration from other famous figures. Since the talk was limited to 3 minutes, I skipped a lot of (quite lengthy) discussions, including coffee grind sizes, water ratios, and water temperature. If you have any questions about the material, feel free to email me!

Summer/Fall 2019: Netskope
Background
From May 2019 to January 2020, I worked at Netskope on the Data/Infra team, both in Santa Clara and in San Francisco. I learned a lot – both academically and professionally. I redesigned and partially rewrote a core part of their infrastructure, which eventually broke out into its own component that would be scaled up over time. This infrastructure was written in Go to replace their aging infrastructure in Python.
