Fix slow and unreliable software

I start by finding where the problem occurs. That means looking at real requests, database work, and error reports before making changes.

Observability helps your team follow what happens inside an application. I can set up logs, performance traces, dashboards, and alerts using Elastic APM and the ELK stack, Grafana, or Sentry. We choose tools that fit your existing system and the problems you need to investigate.

We measure the changes against the original problem. At Bykea, this approach helped reduce a critical API’s p95 response time from about one second to 200 to 300 milliseconds.

What the work can include

• Investigation of slow requests and recurring errors
• Database query improvements
• Observability and application performance monitoring (APM) with Elastic APM, ELK, Grafana, and Sentry
• Dashboards and alerts for application health
• Measured changes and production support
