United States

Message

At Auctor Corporation, I built and maintained full-stack applications for a state transportation agency using C#, ASP.NET, and SQL Server. I worked with business users, QA, and project managers to analyze issues, document changes, and validate fixes.

At Salesforce Marketing Cloud, I developed enterprise applications and services across UI, business, service, and data access layers, and designed MSMQ-driven event trigger systems for Journey Builder. I also build LLM applications in Python with LangChain, LangGraph, and retrieval-augmented generation, and write automated tests as part of shipping.
