On the Operations team I designed and built an LLM-driven IT service request (ITSM) platform that replaces a legacy ServiceNow-based eForm, using Azure OpenAI intent routing, a reusable in-process workflow engine with a VS Code flow editor, and Microsoft Entra ID / Graph approval chains. Also a cross-domain Active Directory password-reset service (Go master, Java / Spring Boot agents) and procurement browser automation. Earlier: a React microfrontend platform (deployment downtime ~2 min → ~1 min) and LLM-assisted invoice matching (~30% less manual entry).
