nullzec · hyberx

context

NULLZEC is the company; the product is Hyberx, an Electron desktop agent that watches the screen and reasons about it in real time. The hard problems are not in any one model call. They are in keeping the pipeline cheap, fast, and predictable across thousands of frames.

what i built

Screen capture, perceptual hashing, and semantic dedup so the orchestrator never spends a token on a frame that has not meaningfully changed.

Multi-model orchestration with speculative parallel execution. Models race; the first viable answer wins; losers cancel.

Took a 2,100-line orchestrator and decomposed it into eight focused modules. Added a 5-level JSON repair stack and Zod-validated IPC across 40+ channels.

engineering choices

Speculative parallel execution is risky without good cancellation. The cancellation primitives were built first, then the orchestration on top.

Zod-validated IPC turned the renderer-to-main surface from a sprawl of stringly-typed channels into a contract that tests can hold to.

outcome

Sub-3 second p95 latency end-to-end. 304 tests covering the orchestrator and IPC surface, so the next refactor will not require re-deriving the invariants.
