I am a Senior Software Engineer with a decade of experience bridging deep machine learning foundations with modern agent infrastructure. Previously a Senior Developer Relations Engineer at Google and a Founding Engineer at Descartes Labs.

Recently, I architected the open-source https://github.com/googleworkspace/cli in Rust—built entirely via AI agents which hit 20k+ stars and #1 on HN. My background spans building petabyte-scale Kubernetes architectures, engineering visual search engines over billions of satellite images, and developing full-stack embedded Rust IoT firmware with custom LoRa mesh networking for endurance races.

I excel at taking systems from 0 to 1 and driving adoption developer experiences. I'm looking for Senior/Staff or Founding Engineer roles where I can tackle complex distributed systems or build secure, agent-first infrastructure.

justinwp··on Dependencies Belong in Version Control
> This is exactly how Google and Meta operate today

I wish it was that great. Works until you need to have a different version than some other piece of code, import a dependency that requires 100 others, or you need to build for some other platform than the "blessed" target. I choose google3 only when I have to or when I am certain of the scope. (I am in DevRel, so I have more options than typical engineers for my work)

justinwp··on How a dangerous stew of air pollution is choking the United States
> The former are much smaller, cooler, and slower burns

Again this has no basis.

The prescribed fire that caused this 300k+ acre fire was supposed to be 1204 acres. That 1204 is the boundary of the possible burn area and the actual area burnt with even moderate intensity was probably planned to be much smaller.

> unison with the landscape and the environment

These are meaningless distinctions.

> the need for localized ecological and geographical knowledge

Fire managers and all of the other resource specialists for the majority of agencies are already local.

> cool fires

not anything unique here. depends entirely on the objectives/goals. if it is to remove juniper in the southwest US, a smoldering fire won't be enough. wildland fire fighters already almost exclusively do the most work at night whether it is a prescribed fire or wildfire. it's a distinction without meaning.

techniques used today are almost always a function of numerous risk calculations and political factors; not some lack of understanding of fire behavior or local knowledge

justinwp··on How a dangerous stew of air pollution is choking the United States
Having spent years working for USFS/NPS etc I disagree with your take that prescribed burns have significantly different goals. The scoping documents always identify numerous benefits to forest health and are created with input from specialists ranging from hydrologists to biologists and archeologists. The techniques are not necessarily relevant to fire intensity which is more a result of current conditions.
justinwp··on How a dangerous stew of air pollution is choking the United States
The escaped prescribed burn in New Mexico this year shows how this really isn't practical today with the Wildfire Urban Interface and current population densities.

I don't share interests with most of my coworkers so I don't really feel like I'm missing out. The bigger issue has been adjustments to how I socialize with others from outside my work circle that share my interests during a pandemic. These challenges are greater for me than WFH.
