Sandipan Kundu
AI Deployment Engineer · Developer Relations
I build AI agents, inference runtimes, SDKs, and developer tools that help teams move from prototypes to production. With 5+ years in Developer Relations, I focus on making complex technology easier to understand, adopt, and ship through clear tooling, documentation, starter kits, and developer programs.

A memory & context engine for AI agents, written in Rust: turns documents, conversations, and tool results into a temporal graph of atomic memories, then serves them back through hybrid search, auto-maintained profiles, and ready-to-inject context digests. Ships as a single binary with an HTTP API, MCP server, and data connectors.
