Architected and built an MVP for a distributed analytical system using a monorepo approach (Python and TypeScript). Led AI-assisted development by structuring agent workflows with specification-driven artifacts and automated refactoring. Designed custom agent capabilities including monorepo exploration via AST/LSP and tools for parsing notebooks and inspecting network traffic. Produced a graph-based synchronization design to coordinate state deltas between compute nodes and agents, and prepared integration-friendly API contracts.
