Systems work focused on email infrastructure, automation layers, and reliability engineering for production workloads.
Built production SMTP routing architecture with DNS-aligned sender configuration, delivery control logic, and retry-safe queue handling for message flows under failure conditions.
Designed backend automation workflows for infrastructure operations, replacing manual execution with event-driven task handling and scheduled system processes.
Implemented system behavior patterns focused on failure detection, isolation, and recovery to prevent cascade breakdown in production environments.
Architecture decisions prioritize controllability over complexity: queue-based processing, separation of routing/execution layers, and explicit handling of failure states instead of implicit assumptions.
