About Me

CTO with 18 years of experience, specializing in building IT departments from scratch, scaling High-Load systems, and optimizing infrastructure costs. Maintained SLA >99% while load increased by 1.9x. Reduced infrastructure costs by 50% through Kubernetes migration and code optimization.

Familiar with HighLoad firsthand. Provided a peak load of 120,000 RPS for an audience of more than 4.5 million users.

Expert in turning chaos into a predictable process. Main competency is building high-load systems with a predictable budget. I know how to find a balance between "perfect architecture" and the "need to launch a product quickly." Effectively managing distributed teams.
