I will build k6 load tests and find performance bottlenecks in your backend

"Will it hold up under real traffic?" is a question you don't want answered by your users at 9am on launch day. I build realistic k6 load tests, run them, and hand you a clear picture of where your system bends and where it breaks.

I performance-test core trading engines WebSocket, protobuf, session-safe connection pooling, thousands of transactions per second so I test the way production actually behaves, not just a happy-path GET request.

What you get:

• Parameterized k6 scripts for your real endpoints and user journeys
• Realistic scenarios: ramp-up, spike, and soak tests (not just a flat load)
• Server-side profiling during the test (pprof and friends) to find the actual bottleneck, not just the symptom
• A capacity report: where latency degrades, where throughput tops out, and what to fix first
• WebSocket / gRPC / protobuf scenarios that generic QA can't touch

Tell me your stack and your target traffic before ordering and I'll scope the right package.
