Hey!

I'm an engineer who has deep experience shipping products and systems across a wide set of problem domains. Here are a few things I've worked on over the years:

  • Data analytics - I spent years co-maintaining an internal fork of Apache Spark, finding some bugs and fixing them upstream as well as making (sadly closed-source) changes to the query planner and core engine
  • Streaming systems - I led a team in building a self-service data streaming platform that was used by airline, manufacturing and government customers for soft realtime applications
  • Computer Vision - I've spent a lot of time building apps and workflows on top of commercial and open source computer vision algorithms, including fine tuning off the shelf models where appropriate.
  • Infra - I've stood up Terraform pipelines to automate AWS deployments, built Kubernetes operators to deploy Apache Kafka clusters, wrote observable code and used perf testing tools to speed up hot paths by >1,000x. I also built this thing.
  • Embedded hw/sw - I built out tooling to flash dozens of NVIDIA Tegra devices that were loaded into aircraft
  • Space - Lots of experience in the Space industry, working with commercial (and non-commercial) satellite imagery and building new products in the GIS space. Ran code on a satellite 🚀🛰️ (yes you better believe it was in Rust!)
