• Strong performance engineering: profiling, load testing, horizontal scaling, capacity planning
• Production reliability ownership: observability, SLOs, incident management, fault-tolerant design
• Multi-tenant SaaS experience, including tenant isolation and noisy-neighbor problems
• Hands-on daily coder with founder-level ownership; comfortable in low-process, high-ambiguity environments

Skills

• Python
• JavaScript/TypeScript (Next.js)
• Kafka or similar streaming infrastructure at scale
• Supply chain or logistics systems exposure (WMS, OMS, TMS, EDI integrations)
