Summary

Senior Backend Software Engineer with over 6 years of experience designing high-load distributed systems, Highload, FinTech, Web3, RMM, AI solutions, and real-time infrastructure. Specialize in backend system architecture, Event-Driven Architecture, microservices, low-latency data processing, and scaling services to hundreds of millions of requests per day.

Over recent years, I have contributed to the development of crypto exchanges, payment platforms, IoT SaaS, AI services, and algorithmic trading systems. My solutions have cut business operational costs by up to 90%, reduced processing times from hours to seconds, decreased false trading signals by 50%, delivered 3000+ RPS processing, and maintained a 99.99% SLA under high load.

My core strength is system design. I design architecture with scalability, fault tolerance, observability, technical debt management, and long-term product maintainability in mind. I apply Domain-Driven Design, Clean Architecture, Event-Driven approaches, CQRS-like patterns, CI/CD, and engineering excellence practices. Beyond development, I actively contribute to technical leadership, architectural decision-making, Code Reviews, engineer mentoring, and translating complex business requirements into scalable engineering solutions.
