Ensure strong governance, privacy, and security controls for enterprise and sensitive data

Performance, Security & Reliability

Optimise LLM performance, scalability, latency, and operational cost through caching, batching, streaming, and token optimisation
Design resilient distributed systems using retries, fallbacks, circuit breakers, and graceful degradation patterns
Implement logging, monitoring, tracing, and observability solutions using OpenTelemetry, Application Insights, Grafana, or similar tooling
Apply responsible AI principles including privacy controls, auditability, bias mitigation, and secure AI implementation practices
Participate in system design discussions and contribute to scalable cloud architecture decisions
