What I'm looking for

I'm looking to build reliable, high-performance GenAI and full-stack software, solve complex model integration challenges, and collaborate with cross-functional teams that value strong code quality, documentation, rapid iteration, and mentorship.

At BlackLine, I build and ship full-stack applications in Python and Java that demonstrate frontier model capabilities. I integrate pre-release model APIs into production software with tool interfaces, telemetry, evaluation harnesses, and cloud deployment strategies focused on performance, reliability, and scalability.

I've diagnosed model integration failure modes and turned complex engineering observations into actionable research feedback and clear documentation. I also build internal automation tools, improve user-facing experiences with Java, TypeScript, and JavaScript, and mentor junior developers while maintaining code-quality and architecture standards.

Earlier at DealerSocket, Revature, and Cambia Health Solutions, I developed backend services, APIs, HR-focused full-stack applications, and customer-facing tools across Java, Python, C#, React, and cloud environments.
