I will perform k6 load and performance testing for your API and website
Expert QA Automation Engineer for Web, API and Performance Testing
About this Gig
Will your app survive launch day? Find out before your servers crash in front of real users.
I'm a performance engineer specializing in k6 load & stress testing for APIs and websites running on a rigorously audited, measurement-validated framework, so the numbers you get are real, not inflated.
What you get:
- Load, stress, spike, soak & breakpoint (capacity) tests
- The metrics that matter: P50/P95/P99 latency, throughput (RPS), error rate
- SLO-based PASS/FAIL verdict against your own targets
- Per-API breakdown + wire-failure & retry visibility flaky backends can't hide
- Tiered report (basic / standard / premium) + raw metrics JSON
- Optional CI integration (GitHub Actions)
The headline deliverable: a breakpoint test that finds your max sustainable RPS exactly how much load your system handles before it breaks.
Large or ongoing testing? Message me first I'll send a custom offer with the right scope, price & timeline.
Note: this measures server/backend capacity (HTTP load) not browser rendering / Core Web Vitals (separate scope).
Don't guess your limits measure them. Send me your endpoints + target load and I'll scope it free before you order.

FAQ
What information do you need to start the load test?
I need your API endpoint URLs, authentication details (API keys/tokens), expected payload examples, and your target load (concurrent users). If you have specific test scenarios in mind, share those too!
Can you test APIs that require authentication?
Absolutely! I handle OAuth, JWT tokens, API keys, and session-based authentication. Your credentials are kept secure and deleted after testing.
How many virtual users can you simulate?
Basic package supports up to 100 users, Standard up to 500 users, and Premium can handle 1000+ concurrent virtual users. Need more? Contact me for custom solutions.
Do you test production environments?
I can test production, but I recommend testing staging environments first to avoid impacting real users. I'll work with you to determine the safest approach for your situation.
What format are the reports delivered in?
You'll receive comprehensive HTML reports, plus a summary PDF highlighting key findings and recommendations.
Can you help fix the performance issues you find?
My gig focuses on identifying bottlenecks and providing recommendations. For implementation assistance, contact me for a custom offer—I'm happy to help optimize your system!
