What I'm looking for

I seek backend engineering roles focusing on scalable architectures, payment systems, and high-load processing with autonomy and technical excellence.

I am a Senior Golang developer with 5+ years building high-performance backend systems, scalable microservices, and payment processing platforms. I specialize in designing robust architectures, integrating complex third-party APIs, and delivering clean, maintainable code as a strong individual contributor.

My work includes leading engineering efforts, optimizing gateway services, and implementing transactional storage and processing with ClickHouse and PostgreSQL. I bring hands-on experience with Kafka, gRPC, Vault, AWS serverless components, and cross-team technical leadership to solve challenging engineering problems.
