What I'm looking for

I'm looking for a mentorship-focused engineering environment where I can contribute to collaborative production software development, learn unfamiliar technology stacks, and continue growing as a software engineer.

At Argo, I improved production software across four development teams, optimized SQL queries to cut execution time by up to 500%, and built Spring Boot REST endpoints for CRUD, reporting, data processing, and auditing.

I'm continuing to build Couch Crasher, a full-stack property rental platform using Next.js, Node.js, PostgreSQL, AWS, Redis, and PostGIS. I enjoy learning unfamiliar stacks quickly and want to grow in a mentorship-focused engineering environment.
