Bijection for Engineering

Retire the admin panel. Keep what it did.

Turn the internal tool with unreviewed production access into operations with a plan and a reviewer.

Get started

Most companies have an internal admin tool with direct production access. It started as a script, grew into a panel, and now support, operations and finance all use it without anyone reviewing what it writes.

Bijection turns each thing that tool did into a declared operation. It shows its plan, checks who may run it, waits for approval when it is risky and records what it changed. Internal apps become views over those operations, not another backend to maintain.

  • Customer data fixes

    Starts: Support asks to correct a customer’s data

    1. The operation shows exactly which records it will change.
    2. Destructive changes wait for an engineer’s approval.
    3. The change and its approver are recorded.

  • Incident timeline

    Starts: PagerDuty opens an incident

    1. Gather recent deploys from GitHub, alerts from Datadog and errors from Sentry.
    2. Put them on one timeline, each item linked to its source.
    3. Attach it to the incident for the review.

  • Service handover

    Starts: A team takes over a service

    1. Preview the repositories, rotas and alert routes that move.
    2. The receiving team approves.
    3. Apply every move as one reviewed change.

  • Production access

    Starts: An engineer asks for temporary production access

    1. Show why, for how long and what it covers.
    2. A second engineer approves.
    3. Access expires on its own at the end of the window.

  • Feature flags

    Starts: Someone changes a flag for a customer

    1. Show which accounts the change affects.
    2. Changes for large accounts wait for review.
    3. Each change is recorded with its author.

  • On-call handoff

    Starts: An on-call shift ends

    1. Collect open incidents, alerts and follow-ups.
    2. Hand them to the next engineer on call.
    3. Anything unacknowledged goes to the team lead.
