Никита Сенько

I’m a Go (Golang) backend developer with 4 years 6 months of experience building high-load systems, focusing on performance optimization and reliable delivery. At CROC, I migrated a critical data import microservice to Go to practically eliminate delays when loading large product catalog files.

I design and evolve scalable architectures and integrate with external services to remove operational pain. I optimized order status synchronization with external partner APIs and executed a migration that reduced manual collision resolution to 0.1%, and I implemented a multi-currency settlement system integrating the Central Bank API with automatic recalculation and alerts for critical fluctuations.

I also prioritize code quality, security readiness, and maintainability. I refactored and expanded microservices to meet updated security standards, improved stability with regular refactoring and unit-test coverage to 78%, and use clean architecture and SOLID principles while working with message queues, caching, and monitoring. I mentor junior developers and enjoy turning complex logic into maintainable systems.
