Building systems that never break under pressure

I'm Praveen Prasad, a Senior Performance Engineer based in Pune, India. For nearly two decades, I've been the person teams call when systems need to handle real-world scale — from payment gateways processing thousands of transactions per second to cloud-native microservices serving millions of users.

My work sits at the intersection of deep technical expertise and strategic thinking. I don't just find bottlenecks — I architect solutions that prevent them. From tuning JVM garbage collection to orchestrating complex 26-leg workflow testing, I bring a holistic approach to performance.

I'm passionate about mentoring the next generation of engineers and leveraging modern tools like Gen AI to accelerate workflows and deliver results faster.
