@rizwantahir
I am a performance tester and software developer specializing in load testing, automation, and AI-driven solutions.
I am a performance-focused software professional with over four years of hands-on experience in performance testing, desktop software management, and full-stack development. I combine practical testing discipline with software engineering skills to deliver reliable, high-performing applications.
I have designed and executed load, stress, endurance, and scalability tests using tools such as LoadRunner and JMeter, and I routinely analyze client-, server-, and application-side metrics with Perfmon, Dynatrace, and AppDynamics. I collaborate closely with development teams to identify root causes and drive performance optimizations across the stack.
On the development side, I build AI and computer-vision solutions using Python, TensorFlow, OpenCV, Flask and Pandas, delivering projects like a face-recognition attendance system and a handwritten equation solver that automate manual workflows and improve accuracy. I emphasize secure data handling, cross-platform deployment, and measurable outcomes such as reduced manual effort and improved reliability.
I bring strong communication, client-management, and test-planning skills, and I thrive in Agile teams where I can combine performance engineering, scripting, and ML knowledge to solve complex, real-world problems. I seek roles where I can continue advancing performance engineering practices and applying AI techniques to production systems.
