$ whoami

Backend and integration-focused software engineering student building production-style services end to end — REST and GraphQL APIs, asynchronous messaging, containerized deployments on Kubernetes — grounded in solid fundamentals in Java, Python, and SQL.

I like understanding how systems actually behave end to end, from a REST endpoint down to what happens on the wire, so I build things to test that out rather than just read about it.
