Hi, I'm Zakhar Vlasenko, a Systems & Performance Engineer and competitive programmer dedicated to building high-performance, scalable, and data-intensive applications. I specialize in C++ and C#, with a strong focus on low-level system architecture, memory optimization, and algorithmic efficiency.

• Silver & Bronze Medalist in the All-Ukrainian Olympiads in Informatics (UOI/VKOI), bringing rigorous algorithmic problem-solving to production environments.
• Developing high-throughput core execution systems, scalable state architectures, and automated data workflows.
• Systems programming, advanced data structures, parallel processing, and query optimization concepts.
• Squeezing every drop of performance out of a CPU, designing lock-free data structures, and continuously diving deeper into distributed systems and database internals.
