Senior Backend/Full-Stack Software Engineer

Backend engineer with production experience in auth, authorization, and user-account systems at scale. At Bloomberg Industry Group I've shipped MFA/reCAPTCHA auth flows, serverless AWS infrastructure, and async microservices handling real user traffic. Strong opinions on secure API design and clean service boundaries. Side project: an agentic RAG system that indexes entire codebases and uses LangGraph to answer structural questions and generate tests. Looking for backend or full-stack roles where I can own meaningful infrastructure and work on hard problems.
