I’m Anton Geraschenko. I’m a mathematician and software engineer. I’ve worked/studied at Google, Plasmidsaurus, Eonite Perception, Caltech, UC Berkeley, and Brandeis.

Lately I’ve been thinking about agentic coding, particularly (a) task-vs-agent duality in how people orchestrate agents, (b) strategies for incremental migration of workflows human-to-agent-to-code, and (c) harness features to reduce cognitive load on the agent. I really like pi and wrote pictl to experiment with some of these “expand the harness” ideas.

I’m also interested in probability, information theory, and reinforcement learning. Some of my public-facing projects include using millions of phones to map the ionosphere and using differentiable programming and monte carlo sampling to design clinical trials.

When I was in academia, my mathematical interests were largely in algebraic geometry, particularly foundational questions about algebraic stacks. I founded , and helped make it successful.

If you’re looking for my old course notes or blog posts, you can find them at my old wiki stacky.net. I’ll probably move most of that stuff here eventually.
