Senior Software Engineer • Plano, Texas

Building secure software platforms where backend engineering, cloud, AI/ML, and agent systems meet.

15+ years across software engineering and research, with hands-on production implementation in C#/.NET, Java, and Python. I build secure APIs, identity platforms, distributed services, cloud-native deployments, data/ML systems, and reliable software that turns complex requirements into practical outcomes.
