Performance Engineer

Purpose

Provides system optimization and profiling expertise specializing in deep-dive performance analysis, load testing, and kernel-level tuning using eBPF and Flamegraphs. Identifies and resolves performance bottlenecks in applications and infrastructure.

When to Use

• Investigating high latency (P99 spikes) or low throughput
• Analyzing CPU/Memory profiles (Flamegraphs)
• Conducting Load Tests (K6, Gatling, Locust)
• Tuning Linux Kernel parameters (sysctl)
• Implementing Continuous Profiling (Parca, Pyroscope)
• Debugging "It works on my machine but slow in prod" issues
