What I'm looking for

I’m looking for a remote-friendly role in fintech or high-scale platforms where I can design microservices, modernize Java (Java 21/virtual threads), build event-driven systems with Kafka, and mentor engineers to improve reliability and security.

I’m a Senior Java / Backend Software Engineer with 8+ years building high-load backend systems for the financial sector. I’m currently a Lead Developer at Alfa-Bank, where I architect microservice platforms and focus on measurable performance, reliability, and modernization.

In my current role, I designed the corporate Digital Profile microservice platform, scaled it across multiple services, and reduced cross-service latency. I led migrations to Java 21 with zero production downtime, re-platformed services from a reactive stack to virtual threads, and moved from Tarantool to MongoDB to lift throughput and reduce infrastructure cost.

I bring deep expertise across the Spring ecosystem, distributed systems, event-driven messaging, and secure development. I’ve also served as an Application Security Champion to establish secure-coding standards, mentored engineers and ran technical interviews, and previously improved release cycles and observability at Revolut, while advancing platform capabilities at Gazprombank.
