Instrument new work with structured logging (Pino), OpenTelemetry tracing, and Prometheus metrics; debug across the Grafana / Tempo / Loki / Pyroscope stack.
Handle PHI safely - apply secure coding practices, use PII-safe span attributes, and flag security concerns during code review.

Work independently on defined features and escalate blockers early; drive small-to-medium initiatives from concept to completion.
