About / Operating System
I am a Wake Forest junior studying Finance and Computer Science, and a Software Engineer at Steward Technologies. I like software that acts in the world: agents that can use tools, products that manage real financial decisions, and systems that still behave when their cleanest signal disappears. My work moves between production fintech, agentic developer tooling, and simulation-heavy side projects.
- Build the real thing.
- Measure what matters.
- Keep the system understandable.
