Full-stack software engineer that really likes automating systems and building intelligent frameworks.
I started out building systems in the Minecraft ecosystem, a quite surprisingly demanding environment for distributed architecture and performance engineering, seeing how Minecraft and Minecraft networks are built. That foundation carried me into a broader full-stack and AI work, where I now spend pretty much all of my time.
I lean on Java for most work, always have, but prefer
TypeScript when there's a web frontend involved. On the frontend it's
React and
Next.js, and on the backend
Spring Boot or Dropwizard, more and more often with Palantir's Conjure to keep the API contract clean between the two. For deployment I'm most comfortable in
AWS.
Postgres is my default database these days, though I spent a long time being "hardcore MongoDB" before that.
More recently a growing chunk of my work has moved into AI, like building RAG pipelines, LLM-powered agents, and the tooling around evaluating and running them. Lately I've been pushing further down that stack, getting into fine-tuning and the lower-level of how these models actually work. There it's mostly Python in that world, which I also reach for outside of AI whenever I'm doing automation scripts or data processing pipeline.
