About
Hi! I'm a software engineer building compliance-first agentic fintech software. I've built distributed financial trading systems, access controls, document processing, observability, proactive lending agents and other tools to make it easier to be in control of your finances. I like to use whatever gets the job done, but I reach for tools like TypeScript, Python, C++, Docker, AWS (ECS/EKS), JavaScript, Docker, Node. JS, and NextJS.
