Bill Weaver

I’m a Senior Software Engineer focused on building AI-powered products that help operational teams automate workflows, generate insights, and take secure actions more efficiently. At Rippling, I led development of Rippling AI, translating complex operational needs into user experiences and reliable backend capabilities.

I build conversational and secure administrative flows using React, Next.js, and Sass, with careful attention to review states, validation flows, and action summaries. On the backend, I design and implement services and APIs in Python, Django, and Node.js, integrating REST and GraphQL with PostgreSQL, MongoDB, and Kafka-based asynchronous workflows to support orchestration and execution across internal systems.

I also design agentic AI workflows using LLM/RAG—enabling multi-step reasoning, tool usage, and context-aware decision making across internal systems. In parallel, I contribute to infrastructure scalability and reliability using AWS, Kubernetes, Terraform, and Chef, and I strengthen production health through observability and debugging with Sentry, BrowserStack, and GitHub-based development workflows.

Before Rippling, I built full-stack features at DoorDash for logistics and dispatch—using Kotlin, Java, Spring Boot, React, React Native, TypeScript, Kafka, Kubernetes, and AWS. Earlier, at Amazon, I developed full-stack software for large-scale platform and internal service workflows using Java, JavaScript, Python, AWS, and PostgreSQL, collaborating end to end with engineers and product stakeholders.
