What I'm looking for

I'm looking for remote Java backend work where I can build and optimize complex systems, apply Spring Boot, Kafka, and Kubernetes, and contribute through clean code, performance, and thoughtful architecture.

I've built Java and Spring Boot microservices for real-time logistics, fintech, and sports analytics platforms. At Alsoft-Center, I developed services for automated match officiating, analytics, streaming, and tournament management, contributing to the project winning Skolkovo accelerator and technology innovation competitions.

At Decart IT-production, I worked on a real-time courier-management platform processing hundreds of events per second, improving latency by 20% through SQL optimization, Redis caching, and hot-path refactoring. I also built event-driven Kafka integrations, WebSocket communication for courier apps, and fault-tolerant gateways for external and government systems.

I value clean code, performance, and thoughtful architecture, and I keep developing through modern technologies and engineering best practices. I enjoy tackling complex distributed-system problems, from data consistency and observability to secure APIs and reliable production delivery.
