I'm an AI forward deployed engineer in financial services, working closely with private markets firms and their portfolio companies to implement the latest in AI and technology. Alongside that I do independent research and build projects under the name JBK Research, mostly at the intersection of markets, technology, and policy.
This site collects my projects and research. More about me, or reach me at jacob.keller@jbkresearch.org and on LinkedIn.
Projects
- MTA MCP Server — A remote MCP server on a free Cloudflare Worker that answers live New York subway and commuter-rail questions for Claude.
- PodINT — A pipeline that turns podcast episodes into a graph of who claimed what, and when, so stances can be tracked across speakers and appearances.
- US Federal Districts Map — An interactive civics map of how the federal government divides the country, with an address search that lists every federal district you live in.
- Why Glass Has Color — A physics-first explainer of glass: what it is, how it is made and worked, and how it handles light, with every color computed from a spectrum.
