Sekou Doumbouya — Principal Infrastructure Engineer
Where architecture
meets execution.
Principal-level infrastructure leader with 20+ years building resilient, cost-efficient cloud platforms. I operate at the intersection of hands-on engineering and strategic architecture — designing systems that scale and developing the engineers who run them.
TL;DR: I'm best leveraged as a player-coach in organizations navigating multi-region architecture, platform engineering, or AI infrastructure at scale.
