01. About Me

Architecting systems
that never sleep

I'm a backend engineer specializing in building high-throughput, fault-tolerant distributed systems. Currently driving engineering excellence as a Senior Software Engineer at Trackier, handling 30K–60K requests per second across systems processing TB-scale data.

My expertise spans microservices architecture, event-driven systems with Apache Kafka, and performance-critical databases like ClickHouse and MongoDB. I believe in writing systems that are simple to understand but powerful under load.

Beyond code, I lead a team of 18 engineers, collaborate closely with the CTO on architecture decisions, and bridge the gap between business requirements and technical excellence.
