Profile: https://flows.cv/evgenykropotin

Senior Staff Software Engineer focused on distributed systems, reliability, and system architecture.

I work on the design and evolution of large-scale platforms, helping organizations move from fragile legacy workflows to resilient, well-structured systems. My role typically spans architecture, technical leadership, and hands-on development - guiding projects from early problem definition to production rollout.

I’m particularly interested in systems where correctness and operational resilience are critical: event-driven architectures, stateful services, and control planes coordinating complex distributed behavior.
