Summary
🤩
Rockstar🎓
Top SchoolNikita Korolev is a results-driven software engineer with ~2 years of professional experience building distributed, low-latency systems and scalable microservices. He has hands-on expertise in Java concurrency, Kafka, Redis and S3-compatible storage, having built a 9-microservice platform with a real-time news feed that sustained ~500ms latency for over 1M daily updates. Nikita has repeatedly improved performance and maintainability—reducing processing times by 60%, shrinking legacy codebases, and splitting monoliths to cut response times by ~30%—while driving high test coverage and performing hundreds of code reviews. Comfortable across DevOps, CI/CD and Agile practices, he also mentors juniors and shapes team conventions. With a strong applied-math background and graduate studies in software engineering, he combines analytical rigor with pragmatic engineering to deliver resilient, production-ready systems. An uncommon detail: he built thread-safe high-throughput components (URL shortener, file storage) that balance atomic concurrency primitives with Redis-backed reliability.
