Building AI products that hold up in the real world.

I’m Sid Jain, an applied AI engineer. I take ambiguous problems from discovery to production—shaping the product, designing the system, and staying for the operational details.

      Added incremental storage support and a series of patches to unify storage backends, implement OPFS, memory, and directory backends, enable single-backend optimizations (strong randomness buffering, writeback hints handling), and adjust patches to publish only journaled PGDATA paths at operation boundaries. This introduces new storage surfaces, updated APIs, and test infra to validate incremental persistence and cross-browser/file-system backends.
