Denis Shiriaev

Principal Systems Engineer & Solutions Architect

20+ years building production systems at enterprise and startup scale — from real-time C++ navigation systems to distributed enterprise search at SAP. I apply agent-assisted workflows and automation-first engineering to ship with the velocity and reliability of teams three times larger.
