Hi! I’m a Performance Engineering Specialist with 11+ years of hands-on experience in diagnosing and resolving complex performance issues across enterprise applications. Over the past 3+ years, I’ve also been teaching and mentoring students and working professionals, helping them break into performance engineering roles, upskill, or prepare for interviews.

I specialize in tools like Apache JMeter, Postman, Locust, and k6, with a strong focus on API performance testing, bottleneck analysis, and debugging inconsistent or flaky test results across staging and production-like environments.

My teaching approach is highly practical and tailored to your goals. Whether you're a beginner, preparing for interviews, or working on real-world challenges, I focus on helping you not just run tests, but think like a performance engineer—understanding systems, identifying issues, and solving them effectively.

In addition, I am a certified IELTS teacher with experience guiding students across all four sections—speaking, writing, reading, and listening. I focus on practical strategies, structured feedback, and building confidence to help learners achieve their desired scores.

Let’s work together through hands-on sessions, real industry scenarios, and focused guidance to help you reach your goals.
