How We Engineer at This Level

This build sits at the same level as our low-level C++ engine work: modifying Chromium and its service worker push pipeline directly, rather than layering a fragile JavaScript workaround on top of it. It was built with a single senior architect owning the patch end to end, with no junior hand-off at any stage.

  1. Push service

    The platform push service wakes the browser and delivers the encrypted message.

  2. Chromium push pipeline (patched)

    Our C++ change reads the decrypted message here, before it reaches any JavaScript.

  3. JSON payload builder

    Origin, message data, timestamp and a de-duplication ID are assembled into a fixed schema.

  4. Client webhook endpoint

    Delivered by POST, with retry-and-backoff if the endpoint is briefly unreachable.

The hook lives in the browser process itself, so delivery does not depend on the tab being open, focused, or on the page’s own script cooperating.

Technical Authority

Engine-Level Push Interception

The common way to react to a push message is JavaScript inside the service worker: listen for the push event, then call fetch() to notify somewhere else. That works until the browser suspends or evicts the worker, or the page’s own script gets in the way of the event. For this build we went a layer deeper — patching Chromium at the point where the browser process already has the decrypted push message from the platform’s push service, before it is ever dispatched into the worker’s JS pipeline. The C++ change reads that message, builds the JSON payload the client needed, and posts it straight to their webhook — independent of whatever the page’s own script does with the event afterward.

Reliable Delivery

Structured Webhook Payloads

A webhook is only as useful as the shape of what it sends. We defined a fixed JSON schema for every push event — origin, message payload, delivery timestamp and a de-duplication ID — and wrote the POST logic with a short retry-and-backoff so a slow or briefly unreachable endpoint doesn’t silently drop an event. Because the hook lives in the browser process rather than a page script, it fires the same way whether the tab is focused, backgrounded, or closed, and it keeps working across upstream Chromium version bumps because it is tracked as a maintained patch, not a one-off edit.

IP & Code Sovereignty

Sovereign Build Pipelines & Turnkey Handover

The client received full ownership of the work: the C++ patch set against our Chromium fork, its complete git history, and a containerized GN/Ninja build recipe so their own engineers can reproduce the exact build on a clean machine. We also handed over the upstream-tracking process we use internally, so future Chromium releases can be rebased onto without rebuilding the patch from scratch. Nothing about running or maintaining this build depends on us afterward.
