Break work into coherent projects and ClickUp tasks.
Clearly communicate trade-offs and propose pragmatic technical solutions.
Production Readiness & Operations
Design and execute safe, reversible database migrations.
Own background job architecture, Solid Queue usage, and operational resilience.
Contribute to observability and monitoring using Grafana and related tooling.
