I will do load and performance testing for your website or API with jmeter and k6
Over deze dienst
Is your website or API slowing down under traffic or launching soon and you're not sure it'll hold up?
I'm a senior performance engineer with 20+ years in QA. I run realistic load, stress and scalability tests with JMeter and k6, then show you exactly where your system breaks and how to fix it not just that it's slow.
What you get:
- Realistic load simulation with ramp-up to your target concurrency
- Response-time percentiles (p90/p95/p99), throughput and error analysis
- Bottlenecks identified with clear, prioritized recommendations
- A clean report your developers and stakeholders can act on
Pick your scope:
- Basic quick smoke load test on one page or endpoint
- Standard multi-scenario load + stress test with a detailed report
- Premium full audit: load, stress, spike and soak against your SLAs
Ideal for SaaS, e-commerce, APIs and web apps.
Not sure which package fits? Send me your stack and expected traffic and I'll recommend the right one before you order.

Veelgestelde vragen
What do you need from me to start?
Target URL or API endpoints, expected user load, any test credentials for authenticated flows, and ideally a staging environment.
Which tools do you use?
JMeter as the core engine, k6 on request. Reports include latency percentiles, throughput, error rates and graphs.
Will load testing crash my live site?
We agree on limits and timing first. I recommend staging or off-peak hours and a controlled ramp-up to avoid disruption.
Do you also fix the issues you find?
I identify bottlenecks and give prioritized recommendations. Hands-on tuning can be scoped as a separate task.
