Summary
🤩
Rockstar🎓
Top SchoolPeyman Mortazavi is a systems-oriented founding engineer with 11 years of experience building high-performance backend and distributed systems, currently based in New York. He specializes in low-level optimization (Zig, C, Go), Kubernetes, and query planning, and has repeatedly translated architectural and algorithmic improvements into orders-of-magnitude performance gains. At Persefoni he cut XLSX processing from 18 minutes to 12 seconds, designed a ReBAC-based centralized authorization service, and sped up new service onboarding from weeks to hours by defining clear resource and failure boundaries. Comfortable dropping into the hardware-near details when abstractions limit progress, he focuses on correctness, observability, and resource-aware execution models that scale in production. Outside engineering he brings unexpected creative energy—acting and musical theater—which surfaces in collaborative, user-focused problem solving.
