Performance Engineer

$15/hr Starting at $40

I help businesses ensure their applications are fast, scalable, and reliable through high-quality Performance Testing, Load Testing, and API Benchmarking. Whether you already have a working JMeter script or need a complete performance engineering solution from scratch, I provide end-to-end support including test design, scripting, execution, analysis, and tuning recommendations.

I specialize in converting functional automation scripts into performance-ready JMeter scripts, including parameterization, correlation, dynamic authentication handling, CI/CD execution setup, and distributed load test configuration. I also help simulate realistic user traffic patterns to validate real-world performance and reliability under peak load, stress, spike, and endurance test conditions.

My testing approach includes defining NFRs (Non-Functional Requirements), workload modeling, environment validation, and performance risk assessment to ensure test coverage aligns with business expectations. After execution, you will receive a detailed report that includes performance graphs, bottleneck identification, KPIs, SLA compliance, and actionable recommendations.

What I Offer

  • JMeter Script Development & Enhancement

  • API Performance Testing (REST, OAuth, Tokens, Headers, JSON/XML)

  • Load, Stress, Spike & Soak Testing

  • Performance Framework Setup for CI/CD (Jenkins, GitHub Actions, Azure DevOps)

  • Monitoring & Analysis using Dynatrace, New Relic, Splunk, Grafana, AWS X-Ray

  • Test Data Strategy & Parameterization

  • HTML Dashboard Reporting and Result Interpretation

  • Tuning Recommendations (Application, DB, Network, Caching, JVM)

Technical Skills & Tools

  • JMeter, LoadRunner, Gatling

  • Dynatrace, New Relic, Splunk, Grafana, AWS CloudWatch, X-Ray

  • Postman, Swagger, Rest Assured (optional)

  • AWS, Kubernetes, Microservices, Docker

  • CI/CD Integration (Jenkins, GitLab, Azure DevOps)

Why Work With Me?

✔ 6+ years of experience in real-world Performance Engineering
✔ Domain expertise in Fintech, Payments, E-commerce, Banking & SaaS platforms
✔ Experience simulating thousands of concurrent users and real-world traffic conditions
✔ Clear communication, documented test approach, and timely delivery
✔ Flexible engagement model — fixed-scope, milestone-based, or ongoing support
