Performance and reliability

Fast under load, calm on launch day, cheaper to run.

I find what makes a system slow or fragile and fix it: queries, caching, queues, infrastructure and front-end performance. Start with a five-day performance audit, get ready for a launch or a big event, or hand over your cloud and deployment pipeline.

Sound familiar?

  • Pages or APIs are slow, and nobody can say which layer is to blame.
  • A launch, campaign or sale is coming, and you're not sure the system will hold.
  • The cloud bill keeps rising, deployments are manual, and nobody has ever tested a restore from backup.

Questions

Where do you start with a slow application?

With measurement, not guesses: real-user data where it exists, then profiling of the slowest pages and endpoints down to individual queries and code paths. The fix list follows the numbers.

Do you only work on new systems?

Most of this work is on existing systems that have grown slow or fragile over time. The aim is to fix what matters most without a rewrite.
