I am a software engineer with a focus on building backend services, ML model management, and scalable data pipelines. At Pony.ai, I designed REST and gRPC APIs in Python and Go, built and optimized storage with PostgreSQL and Redis, and coordinated workflow execution and model deployments. I also implemented CI/CD pipelines using Kubernetes-based Argo Workflows, Jenkins, and Bazel to automate builds and deployments across AI, Perception, and Mapping teams. Before Pony.ai, I contributed to Rocket Mortgage's mortgage platform and Microsoft’s resilience tooling during internships, gaining experience in full-stack development with Spring Boot, React, and cloud-based CI/CD. I enjoy building observable, high-availability systems and mentoring teammates, and I’ve led side projects like an AI onboarding chatbot and an event-driven pipeline that ground responses in internal docs.…I am a software engineer with a focus on building backend services, ML model management, and scalable data pipelines.
