Increased migration speed from 80 to 8,000 users per minute through architectural and technical optimizations. - Increased the first-ride completion metric by 6.7 percentage points and reduced verification team costs by 24.5% by designing and developing the Driver Restoration Flow, enabling over 750,000 users worldwide to restore their accounts. - Improved user status consistency by architecting solutions for major integrations with our services. - Acted as key problem-solver within team, leading incidents and critical compliance-related tasks. - Led system refactoring to simplify future expansion and rebuilt core components using clean architecture principles. - Led major architectural transformations, deprecating legacy code to improve scalability and maintainability. - Mentored 5 new team members.

NW RCAI develops flight information systems providing aircraft crews with essential operational data — including maps, landing procedures, NOTAMs, SNOWTAMs, documents, and chart kits. The platform is used by thousands of aircraft and major Russian airlines such as Aeroflot, Rossiya Airlines, Pobeda, and UTair. Key Achievements: - Designed and developed backend microservices using Domain-Driven Design (DDD) principles; conducted regular code reviews to maintain code quality. - Increased the SLA of critical flight information delivery components to 99.9% by migrating the system to a microservices-based architecture. - Simplified and enhanced the document management system, introducing precise access control and improving stability and scalability by extracting document handling from the monolith. - Actively participated in decomposing the legacy monolith into independent, microservice-based modules. - Led the development of the Flight Information Preparation and Delivery Service, ensuring reliable data processing and timely information distribution.
