Kristiyan is a Principal Engineer with over eight years of experience building and evolving large-scale backend systems in fintech and enterprise environments. He has worked extensively on complex system migrations, helping teams modernize platforms while maintaining reliability at scale. His interests span software architecture at multiple levels — from system-wide concerns such as microservices and distributed systems, to service-level design patterns like clean and hexagonal architecture. He is particularly passionate about CI/CD, developer productivity, and using automation to reduce operational and cognitive overhead for engineering teams. An early adopter of LLM-based systems, he focuses on how AI can be introduced into backend architectures in a practical, controlled, and production-ready way. Through his work and talks, he aims to help engineers better understand emerging architectural patterns and apply them with confidence in real-world systems.
