Services for existing applications

Ruby on Rails rescue for a troubled application

Recurring crashes, stalled jobs and broken integrations can make every release feel risky. We diagnose the immediate failure, restore dependable processing and leave a recovery plan your team can use.

ShopWired: stalled queue recovery and production stabilization

Start with the failure affecting your business

Crashes and timeouts

Trace logs, exceptions and infrastructure signals to identify failing requests, resource pressure and recurring errors. Establish the incident scope and customer impact.

Stalled jobs and broken integrations

Inspect queue state, retries, external API failures and webhook processing. Check duplicate-processing and data consistency risks before retrying or replaying work.

Unreliable deployments

Review release steps, configuration, migrations and rollback options. Identify the changes that make production fail and the access needed to recover safely.

Diagnosis, stabilization and recovery

Diagnose and agree a recovery plan

Document the likely root cause, affected workflows and immediate options. Agree the safest recovery steps, responsibilities and communication cadence.

Stabilize production

Implement the agreed fixes, restore processing and verify critical workflows. Make retries and recovery explicit so a restart does not conceal the underlying problem.

Reduce repeat incidents

Add targeted tests, monitoring and error handling. Separate immediate fixes from the larger upgrade, refactoring or infrastructure backlog.

What recovery leaves behind

We agree access, availability and response arrangements before starting. Start by describing the affected workflow, when failures began and the logs or monitoring available. The initial discussion establishes whether the required incident coverage fits our capacity.

Incident findings and validated fixes

Receive the diagnosis, changes delivered, checks performed and any unresolved risks. Compare the affected workflow before and after the fix using request errors, queue progress or integration consistency. Agree an observation period and document what the evidence does and does not establish.

Recovery runbook and next priorities

Document operational checks, escalation contacts, rollback and replay steps, plus a prioritized follow-up backlog. Agree ongoing maintenance separately when the application is stable.

ShopWired: a stalled queue restored

Analyzed and redesigned DelayedJob handling and dispatching, unblocked the completely stalled queue and eliminated H12 errors that had occurred multiple times per day. Added monitoring and error handling.
