Senior🎓
Top SchoolAlexandr Sidorenko is a backend developer with 11 years of hands-on experience building resilient, production-grade web systems, currently focused on Node.js, RabbitMQ, Redis, MongoDB and k8s in Belgrade. He’s shipped full lifecycle products—from a long-running document management system that automated partner onboarding to a scalable HRTech service that automates tax calculations and receipts—often designing event-driven architectures and queue-based optimizations that improved query performance up to 4x. Early interest in security and CTF organization informs a pragmatic approach to reliability and error recovery, including self-healing process flows and detailed failure reporting for non-technical users. Alexandr’s background spans fullstack React/TypeScript work and deep backend engineering, and he has hands-on experience reducing third-party API dependency to cut costs and improve stability. He combines a lifelong curiosity about computing with a history of community teaching and hackathon wins, and prefers shifting complexity server-side to simplify client experience.
