SAMANTHA LAVRINC
Founder & Lead Software Engineer – Castle Logic LLC
SUMMARY
Pittsburgh-based Software Engineer with hands-on backend development experience and a design background that goes back to 2006. I work in Java, SQL, and CI/CD pipelines, and I'm equally comfortable in React, TypeScript, and component-driven front-end development. I care about the same thing on both sides: interfaces that are intuitive and backend systems that actually hold up. Formally trained in both software engineering and design.
