Production experience with Docker and Kubernetes, plus strong system design skills and sound reasoning about performance, latency, and cost. Working knowledge of PostgreSQL, APIs, queues, and caching. Experience improving platform reliability and performance under production load, including instrumentation, observability, and root-cause analysis. Familiarity with streaming responses or LLM request routing across providers, including fallback and cost considerations. Experience writing application code alongside DevOps or SRE work; comfort contributing to frontend code when needed.
