I’m Aleksandr Klochkov, a Computer Science graduate from the University of South Florida with a strong foundation in game development. I specialize in gameplay systems, real-time rendering, and building immersive, visually compelling experiences. With professional experience working in C++ and modern game engines, I enjoy solving complex technical challenges and collaborating across disciplines to bring interactive worlds to life

Work experience

Microsoft

2025

Software Engineer, User Behavior Analytics

Designed and implemented a User Session Behavior Analytics system using 12+ months of USF student authentication data to model baseline login behavior, detect anomalies, simulate system load, and strengthen security monitoring.

Built a secure data mining and pattern analysis pipeline to process authentication events, process invocations, and file access sequences, ranking behaviors and forecasting rolling session patterns to improve capacity planning and intrusion detection.

Developed a real-time predictive analytics engine that continuously forecasts user activity during live logins, dynamically updating as processes and files are accessed to flag abnormal behavior, detect potential security breaches, and anticipate resource demand fluctuations.
