What I'm looking for

I am looking for a role that values innovation and collaboration, where I can contribute to performance testing and optimization while continuing to grow my skills in a supportive environment.

I am a Performance Test Engineer with over 5 years of experience specializing in enterprise-scale applications across PLM, finance, and e-commerce domains. My expertise lies in developing and executing performance test strategies using tools like JMeter, Dynatrace, and Azure Monitor, ensuring that applications meet non-functional requirements effectively.

Throughout my career, I have successfully translated business NFRs into realistic load models and modular test plans, identifying performance bottlenecks across application, infrastructure, and database layers. I have collaborated closely with developers, DBAs, and DevOps teams to optimize performance, tuning JVM settings and SQL queries to enhance application responsiveness. My commitment to delivering meaningful insights through load, endurance, and spike testing has been a cornerstone of my professional ethos.
